Light Sensitive Photo Resistor

QUICK OVERVIEW

The Light Sensitive Photo Resistor, also known as a photoresistor or light-dependent resistor (LDR), is a passive electronic component that changes its resistance based on the amount of light that falls on it. Photo resistors are used in a variety of applications, including light-activated switches, automatic street lights, and light-sensitive security systems. The photoresistor is made of a material that changes its electrical resistance when exposed to light. When the photoresistor is in the dark, its resistance is high, and when it is exposed to light, its resistance decreases. This change in resistance can be used to control the flow of current in a circuit, allowing for the detection of light levels and the control of light-activated devices.

Description

A photocell, photoresistor or light-dependent resistor (LDR) is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity. A photoresistor can be applied in light-sensitive detector circuits, and light- and dark-activated switching circuits.

A photoresistor is made of a high resistance CdS semiconductor. In the dark, a photoresistor can have a resistance as high as a few megaohms (MΩ), while in the light, a photoresistor can have a resistance as low as a few hundred ohms. If incident light on a photoresistor exceeds a certain frequency, photons absorbed by the semiconductor give bound electrons enough energy to jump into the conduction band. The resulting free electrons (and their hole partners) conduct electricity, thereby lowering resistance.
