TCRT5000 IR Proximity / Obstacle Avoidance Sensor – 5 Pcs

Description

The TCRT5000 Reflective IR sensor photoelectric switch is perfect for line tracking robot car like DIY projects. 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 that is reflected back.

The TCRT5000 can be used to detect the presence of object or any other reflective surface in front it, also with some level of programming it can also calculate the distance of the object in front it. But the distance can only be calculated for short range objects and is also subjected o environmental disturbance.
