Working Principles

The ADPD174GGI-ACEZR7 operates based on the principle of infrared reflection. When an object is within the proximity sensing range, the integrated infrared LED emits light, which is then reflected back to the photodiode. By measuring the intensity of the reflected light, the module can determine the proximity of the object.

For ambient light sensing, the photodiode measures the intensity of ambient light falling on its surface. This information can be used to adjust display brightness or trigger actions based on ambient light conditions.
