Uses of this type of sensor in the automotive industry include piezoelectric accelerometers, piezoelectric force sensors, and piezoelectric pressure sensors. FIGURE. Piezoelectric sensor circuit. The sensor is a voltage generator and has a resistor connected in series with it.
Pressure Sensors - Motorola. A sensor is a device that produces a measurable response to a change in a physical condition, such as temperature or thermal conductivity, or to a change in chemical concentration. Sensors are particularly useful for making in-situ measurements such as in industrial process control.
