Main functions
(1) The water leakage detection system is divided into a host (LoRa GW gateway) and a slave (WLDS-IoT water leakage detection terminal), each host can manage 64 water leakage detection terminals;
(2) Wireless frequency band 433M, long transmission distance, line of sight greater than 1KM;
(3) Ultra low power consumption, 1 18650/2500mAh high-energy lithium battery, with a service life of over 3 years;
(4) The host provides RS485 interface for easy access to third-party remote monitoring systems;
(5) Has good resistance to electromagnetic interference and high system stability;
(6) The system has a simple structure, easy construction, and simple maintenance.
