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 ...

A Rain Detection System was developed using Arduino and C++ to provide a cost-effective and scalable solution for smart rain monitoring. The system uses a resistance-based rain sensor module to detect ...

Tilt sensors are essential components in security alarm systems today. Standalone tilt sensors sense tilt angle or movement. Tilt sensors can be implemented using mercury and roller ball technology, ...
