Solid-state electronics means semiconductor electronics; electronic equipment using semiconductor devices such as transistors, diodes and integrated circuits (ICs). The term is also used for devices in which semiconductor electronics which have no moving parts replace devices with moving parts, such as the solid-state relay in which transistor switches are used in place of a moving-arm electromechanical relay. Examples of solid state electronic devices are the microprocessor chip, LED lamp, solar cell, charge coupled device (CCD).
A thermostat is a component which senses the temperature of a physical system and performs actions so that the system's temperature is maintained near a desired setpoint by controlling the supply of gas or electricity to the heating or cooling system. Thermostats are used in any device or system that heats or cools to a setpoint temperature. A thermostat operates as a "closed loop" control device, as it seeks to reduce the error between the desired and measured temperatures. Sometimes a thermostat combines both the sensing and control action elements of a controlled system.
A thermostat exerts control by switching heating or cooling devices on or off, or by regulating the flow of a heat transfer fluid as needed to maintain the correct temperature. A thermostat can often be the main control unit for a heating or cooling system including central heating, air conditioners, as well as kitchen equipment including ovens and refrigerators.
