Water Leakage Detector: ZDD-004WLW smart water detector using the principle of electrode immersed resistor changes to detect water. Adopts RF 433MHZ/315MHZ technology design with low power consumption and long battery life. Detector separate from the sensor, it effectively prevent the impact of high temperature environment on the product. It has the advantages of high precision and sensitivity, long-term stability and reliability.
It can be widely used in all water storage equipment, prevent forgetting to turn off the tap, save water, save money, protect water resources; remind and avoid your kids play with water and anywhere to detect water leakage area
