Photoresistor - Wikipedia
WEBA photoresistor (also known as a photocell, or light-dependent resistor, LDR, or photo-conductive cell) is a passive component that decreases in resistance as a result of increasing luminosity (light) on its sensitive surface, in other words, it exhibits photoconductivity.

Light Dependent Resistor: A Comprehensive Guide | Electrical4U
WEBJune 19, 2023 by Electrical4U. Contents. A light-dependent resistor ( LDR) is a passive electronic component that changes its resistance according to the intensity of light that falls on its surface. LDRs are also known as photoresistors, photocells, or photoconductors.
How Does an LDR Work? Basics and FAQs - eTechnophiles
WEBMar 23, 2024 · An LDR is a variable resistor that changes its resistance according to the intensity of the light falling on its surface. As light intensity increases the resistance of an LDR or light-dependent resistor decreases. Hence it is called a light sensor. In simple words, it is a type of sensor that senses the intensity of the surrounding light.

LDR - Light Dependent Resistor | Working, Types, Application
WEBAug 15, 2023 · Its resistance decreases with an increase in the intensity of light. It is often used as a light sensor, light meter, Automatic street light, and in areas where we need to have light sensitivity. LDR is also known as a Light Sensor. LDR are usually available in 5mm, 8mm, 12mm, and 25mm dimensions.
Light Dependent Resistor LDR- Symbol, Construction, Working
WEBLDR is a light-dependent resistor. It is also called Light controlled variable resistor, photoresistor, and photo-conducting cell. As the name suggests, its resistance changes when the light falls on it. So, it is an electronic component, that is sensitive to light.
