Electronic Spices Water Sensor Module for Arduino Moisture / Drop / Depth of Water Test - Red Electronic Components Electronic Hobby Kit

This is simple and small portable water level/water droplet identification, detection sensor water that has high-cost performance. Complete water yield and analog conversion, the output value apply to your custom function. It is low power consumption and high sensitivity. It can make better performance with Arduino 328 controller and a sensor relay shield. Water Sensor water level 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. This sensor is supplied to 5V or 3.3V on VCC and GND pins. The pin S will give us an analog value between VCC and GND. So we will use the S pin as analog input connecting Arduino, the value read will be higher depending on the sensor surface is covered with water. This is because the water acts as a conductor, given that the water we use in our deposits not be pure water (H2O), since if water is nonconductive. But rarely we will use this type of sensor to measure the water level in a tank of pure water.
