This is simple and small portable water level/water droplet identification or detection sensor that has high cost performance. Complete water yield and analog conversion, the output value apply to your custom function. It has low power consumption and has high sensitivity. It can make better performance with Arduino 328 controller and sensor relay shield. 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 analog output  values can be directly read by Arduino development board to achieve the level alarm effect.
