Water level sensor is an easy-to-use, cost-effective high / drop sensor recognition that is obtained by a series of parallel wires that are exposed and therefore the water depth can be measured.
Complete analog signal conversion and output analog values can be read directly on an Arduino Development Board to achieve the level alarm.
