How Does a Photocell Work

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.

Photoresistor: The Best Choice for Your Applications

Photoresistor Symbol An international standard and American-standard symbol of photoresistors differ, as shown in the diagram below. The arrow pointing to the resistor circuit symbol is the light energy. The zig-zag line is for older resistor circuit symbols, while the rectangular circuit symbol is for newer resistor circuits. ...

Photoresistors

A photocell or photoresistor is a sensor that changes its resistance when light shines on it. The resistance generated varies depending on the light striking at his surface. A high intensity of light incident on the surface will cause a lower resistance, whereas a lower intensity of light will cause higher resistance.
