The NB-IoT and LoRaWAN wireless water leak sensor consists of two parts: a data collection unit and a water leak sensor. The water leak sensor utilizes the principle of liquid conductivity and employs a 4-probe design to detect leaks. Under normal conditions, the two probes are insulated by air. In the event of water immersion, the probes conduct electricity, triggering an alarm signal. It offers high sensitivity and precise detection of water leakage incidents, and the cable length can be customized according to customer requirements. The data collection unit is equipped with a built-in LoRa module and a high-capacity battery, paired with an external omnidirectional antenna to enhance the transmission and reception of LoRa wireless signals, extending the signal transmission range. It sends alarm signals to the cloud platform via NB-IoT or LoRaWAN networks, and the platform notifies users via WeChat or SMS. This product uses wide-area network communication technology and can operate independently without a gateway, making it suitable for libraries, server rooms, warehouses, equipment rooms, and any other locations requiring water leakage monitoring.
