![]() Two proximity sensors are mounted just below the handle of the door so that when a person opens the door using the handle the proximity sensor shows a change in its output level. ![]() The OUT is connected to the analog input of Arduino. The blue box with the screw is used for the sensitivity adjustments. The diagram above shows interfacing of a proximity sensor the V pin is connected to the 5V and the GND pin is connected to corresponding GND of the Arduino. The proximity sensor module contains a IR LED and a photo transistor whose output is given to an operational amplifier IC like LM358 for proper amplification. For example, a capacitive or photoelectric sensor might be suitable for a plastic target an inductive proximity sensor always requires a metal target. Different proximity sensor targets demand different sensors. ![]() ![]() The object being sensed is often referred to as the proximity sensor's target. A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact.Ī proximity sensor often emits an electromagnetic field or a beam of electromagnetic radiation(infrared, for instance), and looks for changes in the field or return signal. ![]()
