TCRT5000 IR sensor Module (Obstacle Avoidance/Reflective Sensor)

The TCRT5000 is an IR sensor unit module. It has both a Photodiode and a Phototransistor coupled in its package. The photo diode has two pins (Anode and Cathode) which can be used to generate an IR signal. Similarly, the Photo transistor also has two pins (Collector and Emitter) which can be used to read the IR signal...
