What is stat and sensor?

A stat, short for thermostat, is a device that regulates temperature by controlling heating and cooling systems to maintain a desired setpoint. A sensor, on the other hand, is a device that detects and measures physical properties, such as temperature, humidity, or pressure, and converts this information into readable signals. In many systems, a sensor provides data to a stat, which then makes adjustments to maintain optimal conditions. Together, they work to ensure comfort and efficiency in various applications.
