Water Sensor water level sensor is an easy-to-use, high cost of water / water droplets recognition sensor, which is by having a series of parallel lines exposed wire traces measured droplets / water in order to determine the size of the water level. Water to easily convert analog values of analog signals, the output can be directly read development board, to the effect level of the alarm. Specifications: Product Name: water level sensor Operating voltage: DC3-5V Operating current: less than 20mA Sensor Type: Analog Detection Area: 40mm x 16mm Production process: FR4 double-sided HASL Operating temperature: 10 -30 Humidity: 10% -90% non-condensing
