The experiment is for switching an acoustic sounder as a rain alarm after a predetermine time. It may, however, be tinkered for a number of other applications. Needless to say, this is a simple ...

This project utilizes NodeMCU V.2 programmed with Arduino IDE to detect rainfall using Rain Sensor Modules and send notification messages via the LINE API when it's raining. Install the DHT library ...

The rain sensor sends a LOW signal when water is detected. The buzzer sounds briefly to notify the user. The LCD displays a message: "It is raining" when rain is detected. "No rain" when the sensor is ...

Abstract: 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 ...
