Photocells & Photosensors (Daylight Harvesting & Dusk-to-Dawn …

WebA 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. WebPhotoresistor. A photoresistor (also known as a photocell, or light-dependent resistor, LDR, or photo-conductive cell) is a passive component that decreases resistance with respect to receiving luminosity (light) on the component's sensitive surface. The resistance of a photoresistor decreases with increase in incident light intensity; in other ...

WebA solar cell produces power for an electrical circuit while a photocell is a light-activated control switch. Photocells have been used since the mid 1900s in light meters while solar cells have only become popular since 1990. The only commonality between the two is that light is needed for them to work. WebFor spaces with daylight dimming, a dimming profile is applied to the lighting controls in the internal gains dialog. Lighting gains to the space and lighting power consumption are reduced when adequate daylight levels are available or, in the case of continuous dimming, as daylight levels increase. Daylight levels are determined by a sensor in ...
