Rain Drop Sensor Module

Raindrop Sensor Module The raindrop detection sensor module is used for rain detection. This raindrop sensor is also used for measuring rainfall intensity. The rain sensor can be used for all kinds of weather monitoring and translated into output signals and AO. Raindrops Detection Sensor Module for Arduino, etc. The rain sensor can be used to monitor a variety of weather conditions and turned into several fixed output signals and analog outputs. This raindrop sensor module 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 sensor 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 rain sensor module is based on the LM393 op-amp. If you want to know how a rain sensor works, then check out our blog, What is a Raindrop Sensor?
