The KY-022 module is ideally suited to infrared light detection within the range of 700nm – 1mm, typically seen in project robots and remote control receivers.

The data pin outputs HIGH when the sensor is triggered. Working at a low 3.3 – 5V input the module will output HIGH values on detecting a signal and LOW values while not detecting A data LED is mounted onto the board that lights when the sensor is triggered.
