IR Proximity Sensor (Infrared Obstacle Line Sensor)


Infrared Line or Obstacle Detection Sensor Board

SKU: SB-008 Category:


This Infrared Line or Obstacle Detection Sensor Board is perfect for your line follower or obstacle detection robotic car projects. This is the 1 channel board version. When powered, you set detection level by adjusting the on board trimmer potentiometer. You can get the Output data in digital HIGH and LOW when line is detected in the OUT (digital output) pin.

It has an on board comparator circuit with adjustable potentiometer to set the reference/threshold voltage for the infrared detection level. It also has power and digital output LED indicator for easy debugging. The circuit is a pair of infrared emitter and phototransistor which send signal to each other when there is a white/clear surface and blocks any signal when there is black/dark surface.

You can also get a 4 channel module in one board, check out the Line Follower Sensor (Infrared) Board – 4 channels.
