Capacitive pressure sensor
A capacitive sensor is based on the principle that the electrical capacitance of a plate capacitor can be influenced in the following way

With the resistance-dependent temperature sensors, an external voltage must be applied in order to determine a value.
This type of sensor uses the piezoelectric effect. When a piezoceramic material is deformed by pressure, an electrical voltage is formed across it due to charge displacement.

For pressure control to a specific set pressure, the actual pressure must be measured with a pressure sensor.
Radar sensors are mainly used for distance measurement over longer distances and for speed measurement.
This type of sensor emits ultrasonic pulses that are reflected by the surface to be measured and recaptured by the sensor.
