A sensor is a device that detects changes in its surroundings and turns those changes into electrical signals. Sensors are used in many different devices, such as thermostats, smoke detectors, and cameras.
For example, a thermostat has a sensor that detects the temperature in a room. When the temperature changes, the sensor sends an electrical signal to the thermostat. The thermostat then turns on the heater or air conditioner to keep the room at the desired temperature.
A sensor can be used to detect light, heat, or motion.
