Photocell Sensor Suppliers In South Africa

What is a Photocell Sensor?

Photodetectors, also called photosensors, are sensors of light or other electromagnetic radiation.

There are a wide variety of photodetectors which may be classified by mechanism of detection, such as photoelectric or photochemical effects, or by various performance metrics, such as spectral response.

How many lights can a photocell control?

One photocell can control multiple luminaires assuming they are on the same line, just like a manual switch can turn on and off multiple luminaires.

Photocells were developed to prevent the need for someone to go outside and manually turn on outdoor lights every time it becomes dark.

Does photocell use electricity?

The Science of Photocells

There are several types of photocells available, but they all use the same underlying technology, semiconductors, to control electric current.

Under normal conditions, semiconductors won’t conduct electricity, but when they’re exposed to enough light, current starts to flow.

Why battery is used in photocell?

The battery is used for storage of energy to provide electricity in case of darkness. So the cell can work without battery, but only in light. A photoelectric cell converts light energy to electrical energy.

What is the material of photocell?

The photocell’s semiconductor material is typically cadmium sulfide (CdS), but other elements are also used.

Photocells and photodiodes are used for similar applications; however, the photocell passes current bi-directionally, whereas the photodiode is unidirectional.

What is the size of a photocell?

Size: Round, 5mm (0.2″) diameter. (Other photocells can get up to 12mm/0.4″ diameter!) Sensitivity range: CdS cells respond to light between 400nm (violet) and 600nm (orange) wavelengths, peaking at about 520nm (green).
