Rain Sensor House Kit
Build a house that knows when it is raining! A sensor on the roof detects water, and a circuit inside responds with a flashing light and a buzzer. Wipe the roof dry, and the alarm goes quiet. A small adjustment on the sensor board controls how much water it takes to set it off, from a light mist to a heavy downpour. It is a hands-on look at the sensors that help cars, gardens, and power plants respond to the weather.

How Do Machines Know When It Is Raining?
Rain sensors are hard at work all around us. They turn on car windshield wipers automatically and tell sprinkler systems to skip a watering when it rains. Farms, weather stations, and flood warning systems rely on rain and water-level sensors too, using the data to protect crops, forecast storms, and keep communities safe. Each one follows the same simple pattern of sensing a change and triggering a response. On this house, a wet roof sends a signal to the circuit board, and the light and buzzer announce the alert.
For classrooms
The Rain Sensor House Kit is a great fit for classrooms, after-school programs, and camps. Each kit builds one house and arrives individually packaged with all materials and instructions included.
