This device outputs an IR beam and can detect objects. The detection senstivity can be adjusted via a trim pot on the board to calibrate the proper distance for triggering a detection. Because this module is active low, you can use it to automatically trigger a relay module or something similar when an object is detected.
|Digital Output Signal (Pin OUT)||GND on detection, VCC for no detection|
|Operating Voltage||3.3 to 5V|
