IR receiver diode -3mm can be used in object detection applications like line follower,obstacle detecting robots etc.These were used in our IR Sensor Array.IR Photo diode is used to detect the light rays reflected from an IR LED. Photo diode is a reverse biased PN junction diode. When photo diode is exposed to light, electrical resistance across the diode decreases there by increasing the reverse current. If the photodiode is not exposed to light, resistance across the will be high .hence reverse current will be extremely small. This current is known as dark current.
