How does a Rain Detection Sensor Works. The working principle of the Rain Detection Sensor is pretty simple, as you can see in the image below. The PCB is made out of multiple exposed log conductive ...

During rain, the sensor plate elements are bridged by the rain water and hence this analog output gradually changes from 5V to 0V, based on the moisture level between the sensor pads. By this way, the ...

Arduino is a microcontroller board which is generally an Atemga8. The information sent by the rain sensor is processed by the Arduino and controls the servo motor based on the information processed.

This repository contains good resources to getting started with IoT. Here various sensor is used to connect with Arduino Uno and ESP32 and their program is available. A simple Telegram Bot that lets ...

A novel low-cost rain sensor based on a Surface Plasmonic Resonance (SPR) platform has been designed, realized, and tested. The SPR platform has been used to detect the presence of rain by using a ...

The working principle of the water level sensor module is very similar to that of a Rain Sensor. The water level sensor has three pins, runs on 5V power, and gives out the data in analog format. The ...
