In the world of electronics, thermocouples are temperature sensors that are widely used to convert temperature differences in objects into changes in electric voltage.
Thermocouple working principle is quite easy and simple. Basically a thermocouple consists of only two conductor metal wires of different types and their ends are joined. One type of conductor metal contained in a thermocouple will function as a reference with a constant temperature (fixed) while the other is a conductor metal that detects hot temperatures.
