Smart Water Level Sensor with Relay

Smart Water Level Sensor with Relay – Auto Pump Control & High Sensitivity

Optimize fluid management and prevent overflow or dry running with this Smart Water Level Sensor with Relay Control, perfect for applications such as water towers, heaters, fish tanks, ponds, and pumping systems. This sensor automatically activates or stops water pumps when a set level is reached, protecting your equipment and saving energy. Ideal for use in sensitive areas like machine rooms, libraries, garages, warehouses, and archives, it ensures reliability in both residential and commercial environments.

Featuring a normally open (NO) and normally closed (NC) signal output, this sensor provides flexible control logic—whether you're stopping a pump when the water is too high or starting one when it drops below a set point. The device operates on 10–15V DC and supports high-current load switching up to 250V 10A AC or 30V 10A DC, making it suitable for heavy-duty systems. The relay responds quickly and accurately, ensuring minimal lag or false triggers.

With excellent electrical isolation, the sensor is separated from the controller, making it safe to use in wet environments. Its anti-interference design, high sensitivity, and rapid response time make it a dependable choice for automated water level monitoring and control. Whether for aquariums, industrial water management, or remote utility stations, this sensor delivers peace of mind and professional-grade performance.

Use occasion:.
Water towers, water heaters, fish tanks, fish ponds, pumping pumps, the sensor automatically stops pumping when reaching the sensor, or pumping beyond the water level, can control high-current equipment base stations, machine rooms, libraries, garages, warehouses, archives, and other important occasions. Normally open normally closed signal output
Features:
When the water level is higher than the sensor, the relay will act, the pump will stop working or the pump will start to work, with a normally open and normally closed switch, the relay will act, normally open will become closed, normally closed will become open.
Good isolation: the sensor is separated from the controller, not afraid of water; anti-jamming, high sensitivity, rapid response and other characteristics High sensitivity: accurate detection and no false alarm;
