How does a thermal sensor work?

A thermal sensor works by detecting and measuring temperature changes in its environment. It converts thermal energy into an electrical signal, which can then be interpreted to determine the temperature. Common types of thermal sensors include thermocouples, resistance temperature detectors (RTDs), and thermistors, each using different materials and methods to sense temperature variations accurately. These sensors are widely used in various applications such as weather monitoring, industrial processes, and electronic devices to ensure optimal performance and safety.
