Line/Obstacle sensor - TCRT5000
Sunrom Product Code for Ordering:

The TCRT5000 have a compact construction where the emitting-light source and the detector are arranged in the same direction to sense the presence of an object by using the reflective IR-beam from the object. The operating wavelength is 950 mm. The detector consists of a phototransistor. These can be used effectively in different robotic applications.

IR transmitter and receiver integrated into one head TCRT5000, detecting not only if there is obstacle but also the distance as an analog output, and the power consumption is lower on this one. The breakout board design based on the sensor and LM393 with adjustable Potentiometer, so trigger on a setup approaching distance is possible as a digital value by using LM393. You have analog and digital output both on this breakout board.
