Photocell Tutorial! : 7 Steps (with Pictures)

Testing your photocell The easiest way to determine how your photocell works is to connect a multimeter in resistance-measurement mode to the two leads and see how the resistance changes when shading the sensor with your hand, turning off lights, etc. Because the resistance changes a lot, an auto-ranging meter works well here.

A Step-by-Step Guide: Wiring a Photocell Switch Diagram

The light-sensitive element absorbs photons from the surrounding environment and generates an electric current. This current is then used to control the switching of the circuit. When light falls on the photocell switch, the light-sensitive element''s resistance decreases, allowing more current to flow through the circuit.

Exterior Lighting Control Guidance

Continuous dimming available to <1% of full light output. Efficacy (lumens/watt) is maintained over the dimming range. Dimming may extend product life. Dimming presents little color shift. Dimming may delay color shift that occurs over time with phosphor-coated LEDs. Dimming capability typically poses a negligible cost adder.
