NB-IOT, LORAWAN wireless water sensor

La description

NB-IOT, LORAWAN wireless water immersion sensor consists of two parts: data acquisition box and water immersion sensor. The water immersion sensor uses the principle of liquid conductivity and adopts 4 probes to detect water leakage. Under normal circumstances, the two-pole probes are insulated by air. When immersed in water, the probes are turned on to generate an alarm signal. It can detect water leakage events with high sensitivity and accuracy. The cable length can be customized according to customer needs. The data acquisition box has a built-in LoRa module and a large-capacity battery, and is equipped with an external omnidirectional antenna. It can better transmit and receive LoRa wireless signals, increase the signal transmission distance, and send alarm signals to the cloud platform through the NB-IoT, LORAWAN network. The platform notifies users through WeChat or SMS. This product adopts wide area network communication technology and can be used independently without a gateway. It is suitable for all places that require waterproof monitoring, such as libraries, computer rooms, warehouses, and equipment rooms.
