A photocell, also known as a photoresistor or light-dependent resistor (LDR), is a sensor that changes its electrical resistance based on the amount of light falling on it. There are several types of photocells available, each with its own unique applications and features. 1. Cadmium Sulfide (CdS) Photocells
Photocells are basically a resistor that changes its resistive value (in ohms Ω) 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 innacurate. Each photocell sensor will act a little differently than the other, even if they are from the same batch ...
