Description: IR beam sensor module.
Specifications: It comes in really handy to be able to sense an end-stop, or read the pulses coming through a fine aperture wheel. This little module does it all. Mount at the end of a track, and mount something that will block the ir from reaching the integrated IR receiver. Or mount within the radius of a spinning small aperture wheel. The output pin will change in time with the IR light reception or blocking.
Runs on 5V, and you can power it right from your Arduino.
Dimensions: 1.18 in x 0.79 in x 0.67 in (3.0 cm x 2.0 cm x 1.7 cm)
