The required components to build the circuit mainly include breadboard, jumper wires, battery-9V, transistor 2N222A, photocell, resistors-22 kilo-ohm, 47 ohms, and LED. The above photocell circuit works in two conditions like when there is light and when it is dark.
This article addresses a photocell description that includes the process, circuit diagram, forms, and applications of the photocell. The photocell is essentially a kind of resistor that can be used to adjust its resistive value depending on the strength of light. These are cheap, easy to procure as well as specifications in various sizes.
This circuit uses the photocell to detect darkness, triggering the transistor to switch on the LED, useful for automatic night lights. In light, the photocell’s low resistance keeps the LED off. In two conditions, such as when there is light and when it is dark, the above photocell circuit runs.
The semiconductor material is the main component of a photocell. The mechanism of a photocell depends on the type of semiconductor material that changes electrical resistance in response to light intensity. Cadmium Sulfide (CdS) is most commonly used in photocells. As a matter of fact, photocells are sometimes called CdS cells.
