A photocell, also known as a photoresistor or light-dependent resistor (LDR), is an electrical component that changes its resistance based on the amount of light it is exposed to. Photocells are widely used in various applications, from simple household devices like nightlights to more complex systems such as street lighting and security alarms.
Photocell sensors work like a timer switch in that they power light fixtures off and on automatically during a set “time”. They work a little bit differently though than timer switches because photocell sensors sense the natural light of the sun for controlling artificial light output from lighting fixtures. How Does A Photocell Sensor Work?
Also called a "photodetector," "photoresistor" and "light dependent resistor" (LDR). The photocell's semiconductor material is typically cadmium sulfide (CdS), but other elements are also used.
The cell which is used in the photocell circuit is called a transistor switched circuit. The essential elements necessary for the construction of a photocell circuit are: The circuit of the photocell operates in two scenarios which are dark and light.
Some common types of photocells include Cadmium Sulphide (CdS) photocells, Photodiodes, Photoresistors, and Phototransistors. CdS photocells are sensitive to changes in light intensity and are suitable for detecting ambient light levels.
A: Photocells are specifically designed to detect light and changes in light intensity. They convert light energy into electrical energy through the photoelectric effect. As such, photocells are not capable of directly detecting other types of energy like sound or heat.
Photocells are sensors that allow you to detect light. They are small, inexpensive, low-power, easy to use and don''t wear out. For that reason they often appear in …
