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 ...

Now you can find out how hard it is raining outside without leaving the confines of your mancave/womancave. Pictured above is the sensor portion of what [Frapedia] calls his visual rain sensor. Mos… ...

Simple piezo transducers serve as impact sensors that feed an Arduino and count the relative number of raindrops hitting the sensors.

The raindrop sensor detects the presence of rain by measuring the conductivity of water droplets on its surface. The setup involves connecting the sensors to the Raspberry Pi’s GPIO pins.

Raindrop sensors, designed for rain detection and intensity measurement, find applications in weather monitoring, while the Smart Dustbin contributes to environmental improvement by automatically ...
