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.
