Technical Explanation for Photoelectric Sensors
Operating Principles (1) Properties of Light Rectilinear Propagation When light travels through air or water, it always travels in a straight line. The slit on the outside of a Through-beam Sensor that is used to detect small objects is an example of how this principle
A photocell is a circuit element inside the ambient light sensor (ALS) that converts incident radiant energy into an electrical signal for daylight harvesting or dusk-to-dawn control. It''s also referred to as a photosensor or photocontrol which, however, technically describes the whole sensing system.
