Since sensors cannot replicate an ideal transfer function, several types of deviations can occur which limit sensor accuracy: Since the range of the output signal is always limited, the output signal will eventually reach a minimum or maximum when the measured property exceeds the limits. In telecommunications applications (cell phones & PDA™). A proximity sensor detects the presence of objects that are nearly placed without any point of contact. Light sensors are also known as photo sensors or photoelectric devices, since they convert photons into electrons. In practical applications, these three sensors are often made differential to increase linearity and reduce the additional error caused by electromagnetic attraction. The most frequently used types of sensors for making electrical projects are classified based on the quantities, namely IR (infrared), speed, PIR (passive infrared), temperature, touch, ultrasonic sensors. One of the major implementors of MEMS technology is the automotive industry. , recording, display and control, it is widely used in industrial automatic control systems.
