Sensors are used to sense things, like motion, humidity, rain, light, and temperature. This information is transmitted wirelessly to your home automation computer, and then is used to create events that control other devices, or group of devices in your home. For example, you could use a wireless temperature sensor in a room to control when a portable heater turns on and off. A motion sensor could be used to turn three lights on when someone enters your office, for example.
