Water Level Sensor with Relay Output, 10-15V DC

This water level sensor switches a relay when the water rises above the sensor, so you can automatically start or stop a pump. Its normally open and normally closed contacts let it control higher-current equipment for water towers, water heaters, fish tanks and ponds, or raise a leak alert in machine rooms, garages and storerooms.

Key features

• Relay switches when water reaches the sensor
• Normally open and normally closed outputs for pump start or stop logic
• Sensor is separate from the controller for good isolation
• Relay contacts rated up to 250V 10A AC or 30V 10A DC
• Low working current

Specifications

• Working voltage: 10 to 15V DC
• Working current: Under 100mA
• Relay load: 250V 10A AC or 30V 10A DC

This sensor runs from a 10 to 15V DC supply, so it does not power directly from a 5V Arduino or Raspberry Pi. Mains wiring should be done by someone qualified. See more sensors and modules.
