When the film is projected, the projector light of the soundtrack hits the photocell. As because of the change in soundtrack levels, there will be a change in the intensity of the sound and so the photo-electric current varies. Then the electric current gets amplified and supplied to speakers. The photocell is also employed in burglar alarms.
The pre-invention of the modern-day photocell was developed by Hans and Elster by giving few modifications to CRT (Cathode Ray Tube). So, this was the invention and a brief history of the photocell. This article explains photocell working, types, circuits, and applications. What is a Photocell?
The breadboard, jumper wires, battery (9V), transistor 2N222A, photocell, resistors-22 kilo-ohm, 47 ohms, LED, and battery are the key components needed to make the circuit. The above photocell circuit works in two conditions when there is light and when it is dark.
The construction of a Photocell can be done by an evacuated glass tube which includes two electrodes like collector and emitter. The shape of the emitter terminal can be in the form of a semi-hollow cylinder. It is always arranged at a negative potential.
In various solar cells. Photocells are also utilized for counting the number of vehicles on the road. Photocells are even employed as sensors as well as switches. Used in robotics domain such as guiding robots to conceal from view in the dark location or else to go along a beacon.
