of-the-line Radio module and all this is enclosed in a functional and elegant casing. It also has optional temperature and humidity sensors. Several ways are available to deploy your device. It can be attached with double-sided tape or two screws whose primary function is to be electrodes. The sensor can be screwed directly in the object that has to be monitored for humidity. Another way to use it can be to put electrodes in a pot of potting soil or in the ground to know when the plan needs to be watered. So, a single device will send two separate data sets and two different alerts, one for the rope and one for the electrodes. The opportunity to connect as many resistive rope sensors as it is needed makes it possible to monitor long distance water supply system in every building. Longer single ropes are also available on demand. Conceived in the spirit of maximizing ease of use and efficiency, every part of the Water Leak Detector has a function. Functional and elegant white (Black optional) plastic casing blends into the background Long Battery life with a Lithium Thionyl Chloride battery (over 5 years) Battery replacement requires no tools and is done in seconds 1 Connection of the water rope sensor by jack which can be extended by as many ropes as needed to cover the desired area Two additional electrodes can be used to secure the device V1.0 Kimo Boissonnier 05/03/2021 Water rope sensor Jack connectors Figure 1Water Leak Detector, Top View Figure 2Water Leak detector, Bottom View Electrodes 2 V1.0 Kimo Boissonnier 05/03/2021 Wireless communication system Measurement data is sent using the 2.4 GHz mesh network of the Wirepas system. Collected data is sent automatically through the gateway according to your specifications. All the configuration is done remotely. Water Leak Detector Secured Payload Application Data Schematic Wirepas diagram The Custom Wirepas firmware designed by Promistel, PWS for Promistel Wirepas System, is supplied with all our sensors. Data packets are configurable: frequencies, alert threshold. Sensor data can be polled, collected at a given interval, or triggered by events you will have defined. 3 V1.0 Kimo Boissonnier 05/03/2021 Data Format The data sent by water leak detectors are from Source End Point 111 and with destination End Point according to the data type. The software is based on PWS, for a full list of PWS commands, please reference to the PWS documentation. Here is a short brief of the messages that the device will send. Descriptor (EP 0) This descriptor is a set of data describing the hardware and the configuration of the device. Param 1 (4 bytes) : the PWS version (A.B.C.D) Param 2 (16 byte) : a string, the name of the board hardware Param 3 (4 x 4 bytes) : the values of the sensorPeriod registers. Param 4 (8 x 1 byte) : list of the supported application commands. 8x Param 5.1 (1 byte) : supported sensor (End point) Param 5.2 (1 byte) : sensor option flags The possible sensor option flags are :

0x01 : an offset is set for this sensor 0x02 : an alarm is set for this sensor Alarm message (EP 6) These messages are the result of the alarms configuration (see command 21) Param 1 (1 byte) : Destination EP of the sensor that has generated the alarm Param 2 (1 byte) : The alarm status. The possible alarm status are :

0 : ALARM OFF 1 : ALARM HIGH 2 : ALARM LOW Temperature (EP 112) Signed short: Integer representing the temperature in 100th of degree. Humidity (EP 114) Unsigned short: Relative humidity in 100th of %. Shock detection Extended (EP 127) Param 1 (unsigned byte): the state:

* 0: sensor was stationary, and it is still stationary.

* 1: sensor was stationary, and it is moving now.

* 2: sensor was moving, and it is stationary now.

* 3: sensor was moving, and it is still moving. Param 2 (unsigned short): move duration in seconds. (Meaningful for state 2 & 3) Param 3 (unsigned byte): number of moves. (Meaningful for state 2 & 3) Param 4 (3 signed bytes): acceleration state (One byte per axis X/Y/Z - Meaningful for state 0 & 2) Acceleration value is the MSB of a 12 bits value. And the result is in mG. 4 V1.0 Kimo Boissonnier 05/03/2021 Water Leak Terminal (EP 136) This value is for the pads in the casing Param 1 (signed int): The ADC value measured between the pads Water Leak Rope (EP 137) Param 1 (signed int): the ADC value measured within the structure of the rope Starting your product To start using your device, you only need to plug the Battery in the holder. Open the casing and push the battery in, like in the picture and close the casing again. Connect the Water Rope. The device will connect automatically to the network and send 5 Using the product Place the device with its electrodes on the ground where a water leak may occur, attach the water rope to cover additional area. Both will alert separately. Once an alert occurs, a notification also will be sent once to water rope is dry or that the V1.0 Kimo Boissonnier 05/03/2021 Technical Specifications RADIO INTERFACE Frequency Transmission power ISM (Non licensed) 2,4 GHz Wirepas Mesh Network (2.36 2.48GHz) 10dBm Application data protocol PWS (see corresponding documentation) Hardware security 128 bits AES ECB/CCM/AAR symmetric data encryption Range SENSORS Water leak sensor From 20 to 40 meters (depending environment) Detection of humidity from terminal resistive humidity contactors and from water leak rope with Jack connectors Accuracy: 2 %RH Resolution: typically, 0.01 %RH Values send from the Water leak sensor via PWS Water leak terminal: the ADC value measured between the pads Water leak rope: the ADC value measured within the structure of the rope 3D Accelerometer Values sent from the 3D Accelerometer via PWS Temperature and humidity sensor (optional) Detection of inertial events 2g/4g/8g/16g (1Hz to 5.3kHz) The state:
