Hengjiaan Rain Water Level Sensor Modules for Arduino (2Pcs)
Descripition: Water Sensor is an easy to use£¬ cost effective high level/drop recognition sensor£¬ which is obtained by having a series of parallel wires exposed traces measured droplets/water volume in order to determine the water level. Easy to complete water to analog signal conversion and output analog values can be directly read arduino development board to achieve the level alarm effect. 1£¬ Water level sensor 2£¬ Operating voltage: DC 3-5V 3£¬ Operating current: less than 20mA 4£¬ Sensor Type: Analog 5£¬ Detection Area: 40mm x 16mm 6£¬ Production process: FR4 double-sided HASL 7£¬ Operating temperature: 10'C-30'C 8£¬ Humidity: 10%-90% non-condensing
