Raindrops Detection Sensor Module
Rain Sensor module allows to measure moisture via analog output pins and it provides a digital output when a threshold of moisture exceeds. By using microcontrollers or ADC ICs (Arduino and PIC) it's fairly easy to convert the analog output from the sensor to digital values. This Rain Drops Sensor can be directly read by an Arduino or a comparator circuit if you wish to use it as a rain detection alarm. It can be used to monitor a variety of weather conditions.

Specification
Description
A raindrop sensor is basically a board on which nickel is coated in the form of lines. It works on the principle of resistance. The Raindrop Detection Sensor module is an easy-to-use and low-cost drop recognition sensor. The sensor works through a series of exposed parallel traces onboard which produces electrical variations when drops or water volume changes.Rain Sensor module allows to measure moisture via analog output pins and it provides a digital output when a threshold of moisture exceeds.
