The photocell circuit diagram is one of the most important components of any electrical engineering project. Photocells are small, sensitive devices used to detect changes in light levels, and they're found in everything from cameras and alarms to streetlights and medical equipment.
Also called LDR, photoresistor, photoconductive cell. They are resistors that change value with light. More light means low resistance. Less light means high resistance. In diagram 1 we can see a basic photocell. Photocell has special pattern. Photoconductive material placed in snake-like shape between two metal parts on ceramic base.
The photocell used in the circuit is otherwise called the transistor switched circuit as a dark sensing circuit. Breadboard, jumper wires, battery-9V, transistor 2N222A, photocell, resistors-22 kilo-ohm, 47 ohms, and LEDs are the necessary components to construct the circuit.
First fully explained by Albert Einstein in 1905, the photoelectric effect essentially boils down to this: light can be converted into energy. Photocells use a light-dependent resistor (LDR) to work. If you've ever looked at one close up, it's the part with the squiggly lines on it (see the image below).
Photocells come in many sizes with small 3 mm to big 25 mm. Most common size is 10 mm. Small ones are used in small space like card reader but is not good for high power. Some photocells sealed tight in harsh conditions. Diagrams 3 to 8 show light activated switch circuits using photocell and relay. Diagram 3 shows basic circuit.
PbS (lead sulfide) photocells work like visible light ones but only in infrared range. A phototransistor is a special part that can sense light and amplify signals like a mix of photodiode and transistor. When light hits it, a small current is made and then amplified so it can detect even tiny light changes.
