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.
Photocells are also called by many other names including photoconductive cells, light-dependent resistors (LDR's), and photoresistors. They are variable resistors with an extremely wide range of resistance values (up to hundreds of orders of magnitude) that are dependent on the level of incident light.
A photoresistor or photocell is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity. A photoresistor can be applied in light-sensitive detector circuits, and light- and dark-activated switching circuits. It's also called light-dependent resistor (LDR).
The primary characteristics of a photo-cell are its small size, low power consumption, affordability, and ease of usage. These are commonly utilized in appliances, toys, and gadgets for the reasons listed above. The term Cadmium-Sulfide (CdS) cells are widely used to describe these sensors. LDRs and photo resistors make up these.
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.
A Photocell is basically a resistor that changes its resistive value (in ohms) depending on how much light is shining onto the squiggly face. They are very low cost, easy to get in many sizes and specifications, but are very inaccurate. Each photocell sensor will act a little differently than the other, even if they are from the same batch.
