Grove infrared detector v1.2: the RPR-359F sensor in action

This Grove compatible module connects to a digital output on the Grove Base Shield or Mega Shield. Once powered, its RFR-359F photo-reflector emits infrared light which is reflected by any object in its predetermined range (adjusted with the potentiometer). The sensor status varies according to the detection threshold value. An indicator LED lights up bright red when an object is detected, and goes off when there is nothing.

Applications of the IR detector

With such a sensor, you can design an automatic counting system (on a production chain, for instance), a line-following mobile robot, or an optical encoder. Of course, the 101020175 will have its place in any detection and surveillance systems.
