The rain sensor module is a simple instrument for rain identification. It tends to be utilized as a switch when raindrop falls through the sprinkling board and furthermore to gauge precipitation force. The module includes, a rain board and the control board that is discrete for more comfort, control pointer LED and a movable affectability however a potentiometer.
The analog signal is utilized in discovery of drops in the measure of precipitation. Associated with 5V control supply, the LED will turn on when acceptance board has no rain drop, and DO output is high. While dropping a little sum water, DO output is low, the switch pointer will turn on. Get over the water beads, and when reestablished to the underlying state, yields abnormal state.
