The device is a LoRaWAN™ device compatible with LoRaWAN™ protocol (Class A). When the R313W sensor detects the leak, it will send an alarm message to the gateway. When the sensor detects no leaks, it will send a message that shows no leak to the gateway.

Features

•LoRaWAN™ Class A compatible
•2*3.0V CR2450 button battery power supply
•Water leak detection
•Apply SX1276 wireless communication module
•Frequency Hopping Spread Spectrum (FHSS)
•Configuration parameters can be configured through a third-party software platform
•Applicable to third-party platforms: Actility / ThingPark, TTN, MyDevices / Cayenne
•Low power consumption and long battery life Improved

* Actual range may vary depending on environment.

* Battery life is determined by sensor reporting frequency and other variables
