Introduction LAS-604V3 is a temperature sensor that utilizes LoRaWAN to periodically report temperature. The temperature measurement is through PT100 probe. For forcing various requests of demand, LAS-604V3 supports two operation modes, mode A and mode B. Mode A is hourly report that temperature is reported or recorded every hour. Mode B supports temperature measurement every 30 seconds, 1 minute or 2 minutes, depending on setting. In addition, LAS-604V3 will retrieve date time for synchronous from server at boot up which make sure the accuracy of report time period.

LAS-604V3 can be opened by simultaneously holding and pressing two places in red circle of following figure. A battery holder is inside LAS-604V3, as Figure 2. The supply voltage of battery is 3V. Figure 1 Open LAS-604V3 Figure 2 Battery Holder kiwitec Confidential Documentation 2 There is a wakeup button, SW1, which is used to wakeup LAS-604V3 when it enters deep sleep mode. Figure 3 Wakeup Button There is a jumper inside LAS-604V3 for selecting operation mode of LAS-604V3. Figure 4 is an example which sets LAS-604V3 to Mode B. MODE B MODE A Figure 4 Mode Selection Jumper kiwitec Confidential Documentation 3 3. Device Setup Device Activation:
First step is created a node on LoRaWAN Network Server. The Device EUI, Application Session Key, and Network Session Key will get from product supplier. Application must set to LAS-602/4 and Activation and LoRaWAN Class should be set to ABP and Class A separately. Note: Due to LAS-602/4 sending periodically report at each clock, the downlink window is recommended to set to RX2 for preventing from data collision. Figure 5 Device Activation Gateway Notice:
Another notice is that make sure the Gateway frequencies setting is same as LAS-604V3. And the address of packet forwarder setting must be set to LoRaWAN network server correctly. Figure 6 Gateway Setting kiwitec Confidential Documentation 4 kiwitec Confidential Documentation 5 Temperature Report in Platform:
The temperature report is under application of LAS-602/4, as following figure shows. Figure 7 LAS-602/4 Report kiwitec Confidential Documentation 6 4. Report and Data Format 4.1. Mode A LAS-604V3 reports temperature and alarm through LoRaWANs uplink. By default, LAS-604V3 will send a temperature report every hours. In addition to temperature report, LAS-604V3 will read temperature every 5 minutes by default and compare read value with allowable temperature range. If read temperature is out of allowable temperature range, an alarm will be sent. Besides, the allowable temperature range can be set by downlink command. Except temperature and status report, a LoRaWAN MAC command, DeviceTimeReq, is sent from LAS-
604V3 to server for time synchronization. Figure 8 depicts the entire sequence from power on.

Mode B There is one uplink data type of LAS-604V3 for reporting temperature records and 3 downlink data type for remote settings whose are manually offset setting, interval time/record period, and single mode (Mode 1) setup. The formats of these data types are described at following section. 4.2.1. Temperature Report (Uplink) Temperature report is sent by LAS-604V3 at every predefined period. The period can be changed by downlink command. The length of temperature report depends on how many temperature records in a single report. Temperature Report:

Explanation of Symbols DANGER These entries are actions that absolutely under no circumstance should be taken. The taking of such an action may cause serious personal physical damage or death. CAUTION These entries are actions that if taken may lead to physical injury or damage to persons or things. DANGER To Prevent Serious Accidents Do not disassemble, repair or modify the unit and/or accessories. Do not use the unit in any environment that is exposed to chemicals and harmful gases. Doing so may cause corrosion and/or other danger to the unit. Also, coming in contact with hazardous substances may cause bodily harm to the user or people nearby. Do not handle the unit, remove batteries or cables with wet hands. This product has been designed for private and/or industrial use only. It should not be used in situations where strict safety precautions are necessary such as with medical equipment, or in systems directly or indirectly connected with human life or well-being. Do not drop or expose the unit to a strong impact. kiwitec Confidential Documentation 15 Do not cut or process the cords for the communication cables. Also, do not twist, pull on or swing any of the cords. To prevent damage to the unit from static electricity, remove static electricity from your body by touching metal around you (such as a door knob and window frame) before touching the unit. Place and store the unit and accessories out of the reach of children. We are not responsible for any damage, malfunction or trouble, whether direct or indirect, caused by the use of our product. Do not use any battery, sensor, or cable other than those specified by Kiwi technology Inc. Do not put anything on top of the cable or the unit. This may cause overheating. Make sure that sensor and cable plugs are all inserted fully, so as not to cause an improper connection. Also, when unplugging the cable from the unit, do not pull the cord, but hold the connector to disconnect. If the unit produces heat, emits smoke or a strange smell, or makes unusual noise, immediately remove the batteries and stop using it. If the unit is not to be used for a long period of time, remove batteries. Leaving batteries inside the unit may cause battery leakage and malfunction. Install new batteries when starting or re-starting to use a unit. Do not attach non-isolated thermocouple sensors to objects connected to a live voltage. This may cause a short circuit or an electrical shock. kiwitec Confidential Documentation 16 CAUTION Do not place or store in the following areas:
Areas exposed to direct sunlight Areas subject to direct flames or heaters, as well as areas in which hot air accumulates and creates extremely high temperatures Areas exposed to static electricity Areas exposed to strong magnetic fields Areas exposed to water leakage Areas subject to condensation or wet areas Areas exposed to excessive vibration Areas exposed to excessive smoke, dust or dirt. CAUTION Other Precautions:
Use the unit in the specified operating environment. Do not use it for any purpose other than for which it was designed. Condensation may occur inside the case when a unit is moved from one environment to another where there is a great difference in temperature. Do not use the unit in wet areas or places exposed to water such as bathroom. Do not insert any foreign objects into any of the units' jacks. If the unit gets dirty, wipe it with a clean cloth. Make sure to remove dust and dirt from plugs of any cables. Battery terminals may provide insufficient contact due to age or vibration. This may lead to data loss. Please note that this document has been written based on the presupposition that details about contracts with an Internet provider, specific network environments and the set-up of any other necessary equipment to enable network connection has already been taken care of by the User and that connection has been confirmed as workable. Kiwi technology Inc. shall not be responsible for any damages which a contractor, a user or a third party may suffer, whether direct or indirect, due to the inability to communicate or use communication devices. CAUTION Notices about Sensors:
Do not connect any sensor to the unit other than those specified by Kiwi technology Inc. Make sure to use sensors within the measurement range indicated in the specifications for that sensor. Do not connect the sensor to any data logger other than those specified by Kiwi technology Inc. Do not expose the sensor to a strong impact. This may adversely affect measurement accuracy and cause damage or malfunction. kiwitec Confidential Documentation 17 When the sensor is not to be used for a long period of time, please store it at normal temperature and humidity. The included sensor is not water resistant. If the sensor gets wet, immediately remove the sensor from the unit and wipe it with a clean cloth as soon as possible. Then allow the sensor to dry in normal room temperature before using it again. Do not use the sensor on the human body. Temperature-Humidity Sensor If extremely severe temperature changes occur, it may result in large errors in humidity measurement. Once the sensor's temperature becomes stable, the measurements will return to normal. The temperature-humidity sensors will with normal use experience losses in precision and sensitivity over time due to degradation. If the sensor is being used in an unsuitable environment (smoky or dusty places) it may be necessary to change the sensor sooner. Do not expose to condensation, dampness, corrosive gases, or organic solvents. kiwitec Confidential Documentation 18
