Water Leak Detector with Temperature and Humidity Sensor

The R718WBA is a wireless communication device that detects ambient air temperature and humidity and non-locating leak detection. The R718WBA detects the temperature and humidity of the air. At the same time, it detects the presence or absence of water leakage through the 2-core non-locating leak detection sensor line, and transmits the detected data to the gateway through the wireless network. The SX1276 wireless communication module is used.
