The Raindrops Detection Sensor module is an easy-to-use and low-cost drop recognition sensor. The sensor works through a series of exposed parallel traces on board which produces electrical variations when drops or water volume changes. 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 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.

It includes a printed circuit board (control board) that “collects” the raindrops. As raindrops are collected on the circuit board, they create paths of parallel resistance that are measured via the op-amp. The lower the resistance (or the more water), the lower the voltage output. Conversely, the less water, the greater the output voltage on the analog pin. A completely dry board, for example, will cause the module to output 5V.

The module includes a rain board and a control board that is separate for more convenience. It has a power indicator LED and an adjustable sensitivity through a potentiometer. The module is based on the LM393 op-amp.

Features :

  • The LM393, use of the wide voltage comparator
