Co to jest?

Pressure sensors are elektromechanical devices that convert mechanical pressure into an electrical signal. They operate on various principles, including piezoresistiva, capacitiva, and strain gauge technologies. The output signal - typically voltage, concurt, or digital communication - can be interpreted by a building management system (BMS) to trigger actions or log data.
