In fact, there is an infrared proximity sensor device in the hand sanitizer machine. The proximity sensor is a device with the ability to sense the proximity of an object, also known as a proximity switch.When our hand approaches the induction position of the hand sanitizer machine, the light emitted by the light-emitting diode inside the sensor will be reflected back to the photosensitive receiver when it touches the hand, and the corresponding switch signal will be output, and the hand sanitizer machine will automatically supply liquid.

Infrared proximity sensors have the advantages of strong resistance to external light interference, high stability, small size, easy installation, and no mechanical parts.
