- Photoelectric cell: a transducer used to detect and measure light and other radiations
- Photosensors or photodetectors are sensors of light or other electromagnetic energy. There are several varieties: *Optical detectors, which are mostly quantum devices in which an individual photon produces a discrete effect. ...
- (Photocells) A photoresistor or light dependent resistor or cadmium sulfide (CdS) cell is a resistor whose resistance decreases with increasing incident light intensity. It can also be referred to as a photoconductor.
- A photoelectric cell
- (Photocells) Light-sensing cells used to activate controllers at dawn or dusk.
- Commonly refered to as dusk to dawn sensors, they do just that, turning on items at a pre-determined lux eg, dusk and off again when it becomes brighter, eg, dawn.
- A device that measures the amount of incident light present in a space.
- A light sensing device used to control luminaires and dimmers in response to detected light levels.
- Automatically switches on the infra-red lights when light levels fall to a preset level.
