We live in a World of Sensors. You can find different types of sensors in our homes, offices, cars, and so on. A temperature sensor is an electronic device that measures the temperature of its environment and converts the input data into electronic data to record monitor or signal temperature changes. Temperature sensors measure the amount of heat energy or even coldness that is generated by an object or system, allowing us to “sense” or detect any physical change to that temperature producing either an analog or digital output.
