產品介紹

This module consists of an infrared emitter/detector. When the emitted

Ibeam hits a reflective surface, it will bounce back and senses by the

detector. When the reflected signal exceeds the threshold level set by a

semi-fixed resistor, as it is used as reference for the comparator

amplifier. The output pin voltage level will go low when reflection is

detected which can be used to control the steering of a robot to follow

a painted line or to count rotations of a motor shaft. Only three

connections are required +5V, Vout and Gnd.

 

Operating voltage: 5V

Output voltage: digital low when activated

Size: 1.64" x 0.42" x 0.40"
