This plaque has two strips of conductive material, very close to each other, but without touching. The first one is the effective sensor, which is a plaque that is exposed to the rain. ![]() The rain sensor used is composed of two parts. Output format: Digital switching output (0 and 1) and analog voltage output AO.Comparator output signal clean waveform is good, driving ability, over 15mA.Anti-oxidation, anti-conductivity, with long use time.Adopts high quality of RF-04 double-sided material. ![]() Rain Sensor module allows to measure moisture via analog output pins and it provides a digital output when a threshold of moisture exceeds. Rain Drop SensorĪ raindrop sensor is basically a board on which nickel is coated in the form of lines. It may, however, be tinkered for a number of other applications. Rainwater detector will detect the rain and make an alert rain water detector is used in the irrigation field, home automation, communication, automobiles, etc. You can also add the alarm circuit to this project. Here is an easy project which will display the rain status, so that we can make some actions for rainwater harvesting or take out our clothes from outside, before its getting wet due to rain. Saving water and proper usage of water is very important. Water is a basic need in everyone’s life. LCD Module (To print the Sensor output).If you know already, please skip this section. ![]() ![]() Before starting this tutorial we should know the below topics.
