TCRT5000 Reflective Optical Sensor IR Infrared Switch

TCRT5000 Reflective Optical Sensor IR Infrared Switch is perfect for line tracking robot car like DIY projects. TCRT5000 is a reflective sensor which includes an infrared emitter and phototransistor in a leaded package which blocks visible light.

When the infrared transmitter emits a beam of light to a piece of paper, if the rays shine on a white surface, they will be reflected and in turn be received by the Infrared detector , and pin S on the module will output a low level; If the beam of light encounters a black line, they will be absorbed, thus the Infrared detector gets nothing, and pin S will output a high level. So this module basically acts like a simple switch when it gets close to a white / black object. You can adjust the sensitivity with the potentiometer on the module.

You have to be about 2.5cm from white paper but some objects you may have to be slightly closer for other objects. This is the module that I used – there are a couple of minor variations to this one but generally they all work the same way.

Features:

• Detector type: phototransistor
• Daylight blocking filter
• Lead (Pb)-free soldering released
• Compact construction
• Senses the presence of an object by using the reflective IR beam from the object
