Let's begin with monarchy. Monarchy was the most common form of government until the 19th century. Monarchy is a form of government in which a single family rules from generation to generation. The power, or sovereignty, is personified in a single individual.
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.
Crank or camshaft position sensors and engine speed sensors are similar devices that operate based on pulse detection and counting. The fundamental components of these sensors include a toothed disc mounted on the shaft, a stationary detector and electronic circuitry (Fig-1).
