Power supply is provided by a solar cell. An integrated energy storage allows operation for several days in total darkness. 1.1 Basic Functionality Three 8-bit A/D converter inputs and 4 digital inputs facilitate multifunctional detector sys-
tems, based on passive sensing components. This allows easy and convenient monitoring of temperature, illumination, etc. or controlling window and door states or supervising input voltages or input currents respectively. Figure 1: STM110C sensor transmitter module 1.2 Typical Applications Building installation Industrial automation Consumer electronics The STM110C module serves the 315 MHz air interface protocol of EnOcean. Together with the transceiver modules TCM200 / TCM210C, this module can be easily integrated into op-
eration and control units for the realization of various application-specific system solutions. The module is part of a powerful RF system solution from EnOcean for operation and con-
trol applications. Because the RF transmitters are self-powered, maintenance-free RF sys-
tems can be implemented. EnOcean GmbH Kolpingring 18a 82041 Oberhaching Germany Phone +49.89.67 34 689-0 Fax

In addition, a user-programmable cyclic wake-up is pro-
vided. After wake-up, a radio telegram (input data, unique 32-bit sensor ID, checksum) is trans-
mitted in case of a change of any digital input value compared to the last sending or in case of a significant change of measured analog values: >5LSB of AD_1 input, >6LSB of AD_0 or >14LSB of AD_2. In case of a triggered wake-up a radio telegram is sent in any case. In case of no relevant input change, a redundant retransmission is sent after a while to announce all current input values. Between the wake-up phases, the module is in sleep mode for minimum power consumption. There is a serial interface which allows to configure several parameters of the module:
- Threshold values of the AD inputs which lead to immediate radio transmission
- Manufacturer code (information about manufacturer and type of device) In case a manufacturer code is programmed into the module and DI3=0 at wake-up the module will transmit a dedicated teach-in telegram containing the manufacturer code. Observe Precautions, electrostatic sensitive devices!

pacitance reduced to 70% of nominal value) of the Goldcap is reduced from 100.000 h to 5.000 h when the temperature is raised from 25C to 65C. 1.6 Ordering Information Type STM110C STM111C EnOcean Ordering Code S3031-D110 S3031-D111 Radio Frequency 315.0 MHz 315.0 MHz Solar Cell Included Not included EnOcean GmbH Kolpingring 18a 82041 Oberhaching Germany Phone +49.89.67 34 689-0 Fax

The active solar area is divided into two to provide independent module power supplies:
V_SC1: Main power supply input. Must be connected to the STM110C solar cell
(small active area) or by another external energy source respectively
V_SC2: Goldcap charging input by connecting to the STM110C solar cell (big active area) The capacitance of the Goldcap may be reduced after long term storage of mod-
ules without energy supply. It may take up to one day of charging until the full capacitance is recovered. Continuous operation at temperatures higher than 50C may decrease the capa-
citance of the Goldcap. This will result in shorter charging times and shorter oper-
ating times in total darkness!

trols the power supply for wake-up timer, microprocessor, HF transmitter and the supply outputs. Power supply outputs Two power supply outputs are available:
a) V_OUT b) V_REF (stabilized reference voltage) The outputs are active after wake-up during the active state of the module to drive an ex-
ternal sensor user circuitry. Wake-up timer The wake-up timer provides user-programmable wake-up time intervals for activating the processor and an external wake-up opportunity (WAKE pins). Features:
Extremely low power consumption during sleeping time period
Cyclic processor wake-up configurable by user through external pin configuration
(CW_0, CW_1)
The sleep mode can be terminated immediately by changing the pin status of the differential WAKE inputs. Note that the WAKE inputs are part of a special capacitor circuitry that offers lowest operating power consumption (current flow at switching over time only). WAKE and /WAKE always have to be operated via switch-over as shown in the following:
GND GND WAKE WAKE WAKE WAKE Figure 4: External WAKE pin circuit A radio telegram is always transmitted after wake-up via WAKE pins!
After transmission the counter for redundant retransmission is reset to a random number in the configured range. See chapter 2.5 for configuration of wake-up cycle times. EnOcean GmbH Kolpingring 18a 82041 Oberhaching Germany Phone +49.89.67 34 689-0 Fax

After that, RF signal transmission is triggered if one or more of the following con-
ditions are met:
a) One of the input values has changed since the last radio transmission (one of the 4 digital inputs has changed or one of the 3 analog inputs has changed equal to or more than a defined value of the total measurement range), or b) Counter for redundant retransmission is elapsed c) The wake-up has been triggered via the WAKE pins After every RF transmission, all measurement values are stored for data comparison at next wake-up time. See chapter 2.5 for configuration of timing of redundant retransmission. RF transmitter The radio transmitter is powered up by the processor when the sending condition is posi-
tive. The output LED is activated temporarily during telegram transmission. EnOcean GmbH Kolpingring 18a 82041 Oberhaching Germany Phone +49.89.67 34 689-0 Fax

GND NC 10 sec. 20%
NC GND 100 sec. 20%
GND GND 110 sec. 20%
Redundant retransmission Via CP_0 and CP_1 an internal counter is set which is decreased at every wake-up signal. Once the counter reaches zero the redundant retransmission signal is sent. CP_0 CP_1 Number of wake-ups that trigger a redundant retransmission NC NC Every timer wake-up signal GND NC Every 7th - 14th timer wake-up signal, affected NC GND Every 70th - 140th timer wake-up signal, affected at random GND GND No redundant retransmission at random A radio telegram is always transmitted after wake-up via WAKE pins!
After transmission the counter is reset to a random value within the specified in-
terval. According to FCC 15.231a) a redundant retransmission at every timer wake-up to determine the system integrity is only allowed in safety and security applications!
In this case the total transmission time must not exceed two seconds per hour, which means that a combination with a 1s wake-up cycle time is not allowed!
If applied in other (non-safety, non-security) applications a minimum of 10s be-
tween periodic transmissions is required. In addition the device has to comply with the lower field strength limits of 15.231e). The limited modular approval of STM110C is not valid in this case. EnOcean GmbH Kolpingring 18a 82041 Oberhaching Germany Phone +49.89.67 34 689-0 Fax

2.7 Radio Telegram of STM110C Frequency range and modulation scheme Because of the very low radiated field strength on average, products based on STM110C
(315.0 MHz) can be approved in the USA and in Canada. The approval requirements can be found in chapter 4 of this paper. STM110C is based on ASK (amplitude shift keying) modulation with a bit rate of 125 kbit/s. Telegram content The payload of the telegram consists of:
8 bit 8 bit 8 bit 4 bit 32 bit AD_2 AD_1 AD_0 DI_3..0 ID Transmission timing The transmission timing of the radio module STM110C has been developed to avoid possi-
ble collisions with data packages of other EnOcean transmitters as well as disturbances from the environment. With each transmission cycle, 3 identical subtelegrams are transmitted. The transmission of a subtelegram lasts approximately 1.2 ms. To optimize data security, each telegram is re-
peated twice within about 40 ms, whereas the delay between the three transmission bursts is effected at random. EnOcean GmbH Kolpingring 18a 82041 Oberhaching Germany Phone +49.89.67 34 689-0 Fax

This external circuitry should easily find place on a small PCB that can be connected upside down to the EnOcean module via the STM dual row header. This allows the realization of very compact sensor units.

Power supply by connecting V_SC1 and V_SC2 to the supplied solar cell or by con-
necting V_SC1 to another suitable external energy source
Configuration of the STM firmware by connecting the input pins CW_0..1 and
CP_0..1 If needed, an application-specific sensor circuitry connected to analog input pins
(AD_0, AD_1, and/or AD_2) and powered by V_OUT, V_REF and GND If needed, connections to digital signal inputs DI_0..3. The digital inputs can also be used for an individual sensor type identification defined by the user. If needed, a changeover switch connected to the differential WAKE pins for provid-
ing spontaneous wake-up If needed, a light emitting diode connected between the LED and GND pins for pro-
viding optical feedback of sending To avoid radio frequency pickup from the environment, strip lines of the user cir-
cuit should be designed as short as possible, and the use of a PCB ground plane layer is recommended. EnOcean GmbH Kolpingring 18a 82041 Oberhaching Germany Phone +49.89.67 34 689-0 Fax

The STM110C transmitter module is supplied with a soldered whip antenna as standard. By using that antenna, very compact sensor equipment can be implemented with good radio transmission characteristics. For mounting the antenna, some notes should be considered to optimize system performance:
For best transmitter performance, the space immediately around the antenna has to be strictly considered, since this has a strong influence on screening and detuning the anten-
na. The antenna should be drawn out as far as possible and must be never cut off. Mainly the far end of the wire should be mounted as far as possible away from all metal parts, PCB strip lines and fast logic components (e.g. the STM microprocessor). Dont short the whip
(/4). For a good antenna performance dont roll up or twist the whip and please draw attention to an overall whip distance of at least 10 mm (20 mm is better) from any PCB strip, ground plane and conductive part or electric part. Note that whip antennas do not show any directional effects under free-field radio-wave propagation conditions (spot-wise radiator). The RSSI voltage output of the receiver mod-
ule can be used for evaluating the influence of intuitive RF optimizations. STM110C: L=150 2 mm, color orange Figure 8: Specification of the whip antenna EnOcean GmbH Kolpingring 18a 82041 Oberhaching Germany Phone +49.89.67 34 689-0 Fax

Since the expected transmission range strongly depends on this system conditions, range tests should categorically be performed before notification of a particular range that will be attainable by a particular application. The following figures for expected transmission range are considered by using a PTM, a STM or a TCM radio transmitter device and the TCM radio receiver device with preinstalled whip antenna and may be used as a rough guide only:
Line-of-sight connections: Typically 30m range in corridors, up to 100m in halls
Plasterboard walls / dry wood: Typically 30m range, through max. 5 walls
Brick walls / aerated concrete: Typically 20m range, through max. 3 walls
Ferroconcrete walls / ceilings: Typically 10m range, through max. 1 ceiling
Fire-safety walls, elevator shafts, staircases and supply areas should be considered as screening. The angle at which the transmitted signal hits the wall is very important. The effective wall thickness and with it the signal attenuation varies according to this angle. Signals should be transmitted as directly as possible through the wall. Wall niches should be avoided. Other factors restricting transmission range:
Switch mounted on metal surfaces (up to 30% loss of transmission range)
Hollow lightweight walls filled with insulating wool on metal foil
False ceilings with panels of metal or carbon fiber
Lead glass or glass with metal coating, steel furniture The distance between EnOcean receivers and other transmitting devices such as comput-
ers, audio and video equipment that also emit high-frequency signals should be at least 0.5m. EnOcean GmbH Kolpingring 18a 82041 Oberhaching Germany Phone +49.89.67 34 689-0 Fax

At the front, the solar modules have a glass covering that protects the photovoltaic layer from the effects of the environment and weather. The rear features contacts for the electrical connection. Handling
Prevent injuries due to the sharp glass edges.
Always handle the modules carefully, avoid damage of the glass edges that leads to glass breakage or glass chips. The layers are sensitive to punctual pressure, scrat-
ching or grinding. During handling and processing, always make sure that no par-
ticles are pushed into the coating. Scratches, imprints or particles pushed into the layer can lead to short-circuiting of the module, thus deterioration.
The processing of the modules with lacquer spray processes or edge grinding could
lead to an impairment of the electrical function of the module (electrostatic influ-
ences). In case of necessary module cleaning, the following cleaning agents are suggested:
Kleenex (200 tissues, Code 7107, D 0261 8930, Kimberly-Clark) / highpure DI- wa-
ter / Ethanol (min. 99,8 Vol.%). Soldering The solar panel has 3 connection pads on the rear side. On one side you will see the minus sign. This is the GND connection. Apparatus Materials

Gluing XE16-508 Loctite 403 Figure 10: Gluing the solar cell Instead of soldering it is also possible to glue the solar cell onto a PCB. It is proposed to use the following adhesives:
a) GE Bayer Silicones XE16-508 (electroconductive adhesive) b) Loctite 403 (to increase mechanical stability) First the XE16-508 is put onto the contact pads of the solar cell. Then a drop of Loctite 403 is put in the middle of the solar cell. After that the solar cell is put onto the PCB. Then the solar cell is pressed onto the PCB ac-
companied by small rotary movements (<<1mm). Wear gloves to avoid finger prints on solar cell!
The curing time of Loctite 403 is only 5 seconds once the solar cell is pressed onto the PCB. Positioning must be finished by then!

The solar module is extremely resistant to temperature effects. But mounting must particularly provide protec-
tion against humidity. The proper choice of suitable sealing material is important. The best method is protection by a transparent cover, mainly important for outdoor appli-
cations. Also well-suited is a casing by silicone (not acrylic!). With every kind of protection solution, it is very important that the cell edges and the metallic contact areas are covered. Figure 11: Examples of solar cell mounting Shade During installation, care should be taken to ensure that the active photovoltaic area is not shaded. The cells (strips), which produce the least current due to shade, determine the total module current. EnOcean GmbH Kolpingring 18a 82041 Oberhaching Germany Phone +49.89.67 34 689-0 Fax

The external energy source must fulfill the following requirements:
Parameter Open circuit voltage Ampacity (Peak) Ampacity (continuous) Max 5.0 Typ Min 2.2 10 1 V mA A Unit When using a battery please take care that the transistion resistance between bat-
tery and battery holder is << 10 to avoid voltage drop!
Wrong polarity will damage the module!
3.7 Learn Push Button There are two fundamental methods for transmitter assignments to a receiver:
1.) Manual input of the transmitter ID into the receiver system 2.) The receiver systems automatically learns the ID of a received radio telegram by a special teach-in routine In the second case please note that cyclic sending sensors can be unintentionally learned, mainly if there are some sensors in operation at the same time. Because of that it is rec-
ommended to implement a learn procedure that is reacting to a dedicated Learn Telegram only. This special learn procedure has to be realized by the system intelligence after TCM200C/TCM210C serial interface. For example this can be realized as follows. Recommendation for the realization of a learn push button:

mitting device with respect to 47 CFR 15.231(a-c) and is limited to OEM installation. The module is optimized to operate using small amounts of harvested energy, such as can be collected by a small solar cell exposed to ambient light. The module transmits short radio packets comprised of control signals, (in some cases the control signal may be accompa-
nied with data) such as those used with alarm systems, door openers, remote switches, and the like. The module does not support continuous streaming of voice, video, or any other forms of streaming data; it sends only short packets containing control signals and possibly data and is typically powered by a solar cell in ambient light. The module is de-
signed to comply with, has been tested according to 15.231(a-c), and has been found to comply with each requirement. Thus, a finished device containing the STM110C radio mod-
ule can be operated in the United States without additional Part 15 FCC approval (approv-
al(s) for unintentional radiators may be required for the OEMs finished product), under EnOceans FCC ID number. This greatly simplifies and shortens the design cycle and devel-
opment costs for OEM integrators. The module can be triggered manually or automatically, which cases are described below. Manual Activation The radio module can be configured to transmit a short packetized control signal if triggered manually. The module can be triggered, by pressing a switch, for exam-
ple. The packet contains one (or more) control signals that is(are) intended to con-
trol something at the receiving end. The packet may also contain data. Depending on how much energy is available from the energy source, subsequent manual trig-
gers can initiate the transmission of additional control signals. This may be neces-
sary if prior packet(s) was(were) lost to fading or interference. Subsequent triggers can also be initiated as a precaution if any doubt exists that the first packet didnt arrive at the receiver. Each packet that is transmitted, regardless of whether it was the first one or a subsequent one, will only be transmitted if enough energy is avail-
able from the energy source. Automatic Activation The radio module also can be configured to transmit a short packetized control sig-
nal if triggered automatically, by a relevant change of its inputs, for example. Again, the packet contains a control signal that is intended to control something at the receiving end and may also contain data. As above, it is possible for the packet to get lost and never reach the receiver. However, if enough energy is available from the energy source, and the module has been configured to do so, then another packet or packets containing the control signal may be transmitted at a later, un-
predictable time. OEM Requirements In order to use EnOceans FCC ID number, the OEM must ensure that the following condi-
tions are met. EnOcean GmbH Kolpingring 18a 82041 Oberhaching Germany Phone +49.89.67 34 689-0 Fax
