AI Customer ServiceAutomatic lighting, such as streetlights, often uses photocell sensors—also known as photoeyes—to sense how much ambient light there is. Once the photocell detects low enough light levels, the light turns on or conversely, rising external light levels will turn the light off. The photocell is made up of a resistor attached to photosensitive plates.
The photocell is made up of a resistor attached to photosensitive plates. As more light hits the plates, the resistance (the amount of current that travels through the resistor) changes, turning the light on and off. This technology is convenient for all types of outdoor locations.
Photocells are also called by many other names including photoconductive cells, light-dependent resistors (LDR's), and photoresistors. They are variable resistors with an extremely wide range of resistance values (up to hundreds of orders of magnitude) that are dependent on the level of incident light.
(The lux is the SI unit of illuminance produced by a luminous flux of 1 lumen uniformly distributed over a surface of 1 square meter). Commercial photocells have good power and voltage ratings, similar to those of conventional resistors.
However, lead-sulphide (PbS) photocells have characteristics that are similar to those of visible light photocells except that they function only in the infrared region. Figure 23 shows the standard phototransistor symbol.
They are variable resistors with an extremely wide range of resistance values (up to hundreds of orders of magnitude) that are dependent on the level of incident light. Resistance in photocells varies inversely with the strength of light that falls on them.
