Smart Water Depth Sensor

The water depth sensor measures the depth of water in a tank or container, and its compact design and wired probe allows for placing the sensor where others may not fit. Ideal for water tanks, aquariums, pools, ponds, and more. 

Lower cost of ownership than other technologies; low-power operation means batteries may last up to 10 years. Carefree maintenance, and low-battery alerts give you advanced warning that it is almost time to replace the battery.
