All you need to know about Temperature Sensors in one place

The most popular and commonly used temperature sensor is the thermocouple. Thermocouples are widely used due to their simplicity, ruggedness, and wide temperature measurement range. They consist of two different metal wires connected at a junction. The voltage produced at this junction is proportional to the temperature difference between the junction and the other end of the wires. Reference: Omega Engineering – Thermocouples
