Don't ever get stuck with a flooded basement or over-fill your water bucket. When the liquid level reaches the sensor it automatically turns the pump on or off. The Water Alarm supplies you with 80mA of output that activates a relay (that you supply). This relay could turn on a sump pump, or in applications where you are filling an area with liquid, it turns off the pump. Sensor and wall transformer included.
