This DIY rain detector alarm kit is a fun and educational hands-on project for any budding scientist or engineer. The self-powered kit allows you to build a working model that detects rainfall and sounds an alarm. Using solar and wind energy, the kit’s solar panel and small wind turbine will generate enough electricity to power the water pump and alarm circuitry. Simply connect the rain sensor, water pump and alarm circuit as instructed in the easy to follow manual. When it rains, the sensor will detect the moisture and activate the pump to simulate rain, triggering the alarm to sound. Kids and adults alike will enjoy experimenting with this solar-powered STEM project that demonstrates principles of renewable energy and basic electronics. A great way to learn through doing.
