LORAWAN wireless water immersion leakage sensor consists of two parts: a data collection box and a water immersion leakage sensor. The water immersion leakage sensor uses the principle of liquid conductivity and uses 4 probes to detect water leakage. Normally, the two poles of the probe are insulated by air. When in the water immersion state The lower probe conducts and generates an alarm signal. It detects water leakage events with high sensitivity and accuracy. The cable length can be customized according to customer needs. The data collection box has a built-in LoRa module and a large-capacity battery, and an external omnidirectional antenna for better transmission and reception. LoRa wireless signal improves the signal transmission distance and sends alarm signals to the cloud platform through NB-IoT and LORAWAN networks. The platform notifies users through WeChat or SMS. This product adopts WAN communication technology and can be used independently without a gateway . It is suitable for libraries, computer rooms, warehouses, equipment rooms and other places that require waterproof monitoring. 1. The definition and function of a liquid leakage sensor A liquid leakage sensor is a security device used to detect whether a certain substance has leaked or overflowed. In homes and commercial places, leak sensors are widely used in kitchens, bathrooms, toilets, basements and other places where water or liquid leaks may occur. Leakage sensors can detect leaks early and notify users in a timely manner through alarm devices or other linkage equipment. This allows users to take timely measures to avoid harm and losses caused by liquid leakage. 2. Working principle of liquid leakage sensor The working principle of liquid leakage sensor is very simple. It is composed of a liquid sensor and an alarm device. Liquid sensors usually use metal or capacitive sensors. When the sensor touches the liquid, it immediately changes the circuit state and transmits the information to the alarm device. Alarm devices usually consist of a buzzer, a red light, etc. After the liquid sensor detects liquid leakage, the alarm device will emit sound and light flashes to remind the user to take timely measures. 3. Application scenarios and precautions for liquid leakage sensors
Liquid leakage sensors can be widely used in liquid leakage prevention, safety prevention, environmental protection and other fields. For example, in homes, it can be used in kitchens, bathrooms, toilets and other places where water leakage is prone to occur; in commercial and public places, it can be used in basements, laboratories, hospitals, libraries and other places.
It should be noted that the liquid leakage sensor can only detect whether liquid is leaking, but cannot prevent liquid leakage. Therefore, in actual use, users should take timely measures to avoid damage and danger caused by liquid leakage.
