What is Overview of Optical Proximity Sensors about?
Optical proximity sensors use light to detect objects. There are several types including direct reflection, background suppression, retroreflection, and through-beam sensors. Direct reflection sensors detect objects by light reflected back into the same housing, while through-beam sensors separate the transmitter and receiver to allow detection over greater distances. Optical sensors offer contactless detection over various ranges depending on the technology used.
