This Raindrops sensor module is used to detect rain. The rain sensor can monitor a variety of weather conditions and convert them into fixed output signals and analogue outputs. It has a PCB on which the raindrops are collected. As raindrops collect on the circuit board, they form parallel resistance paths that are measured by the op-amp. For added convenience, the module includes a separate rain board and control board. It has a power indicator LED and a potentiometer for adjusting the sensitivity. The LM393 op-amp serves as the foundation for the module.
