A thermocouple is a sensor that measures temperature by coupling two metal pieces together. The temperature is measured at a junction between these two pieces of metal which are joined at one end. A small voltage is generated by the metal conductors, which can be interpreted to calculate the temperature. A thermocouple is a simple, robust, and cost-effective temperature sensor available in multiple types and sizes. Additionally, they measure a wide temperature range, making them suitable for a variety of applications, such as scientific research, industrial settings, home appliances, and so on.
