They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they often appear in toys, gadgets and appliances. They are often referred to as CdS cells (they are made of Cadmium-Sulfide), light-dependent resistors (LDR), and photoresistors.

A photoresistor (also known as a photocell, or light-dependent resistor, LDR, or photo-conductive cell) is a passive component that decreases resistance with respect to receiving luminosity (light) on the component's sensitive surface. A photocell is a circuit element inside the ambient light sensor (ALS) that converts incident radiant energy into an electrical signal for daylight harvesting or dusk-to-dawn control. It's also referred to as a photosensor or photocontrol which, however, technically describes the whole sensing system.
PHOTOCELL STREET LIGHT PHOTO SWITCH SENSOR AUTO ON OFF SWITCH AC 220V
This is a very small light sensor. A photocell changes (also called a photodetector, photo resistor, CdS or photoconductive cell) resistance depending on the amount of light it is exposed to.These little sensors make great ambient light triggers (when light in the room turns on, do something). Also, each sensor will be different. As the light level increases, the analog voltage goes up even though the resistance goes down: Vo = Vcc ( R / (R + Photocell) ) That is, the voltage is proportional to the inverse of the photocell resistance which is, in turn, inversely proportional to light levels.

Overall Pick Keilton 120V AC Dusk to Dawn Photocell Light Sensor, Outdoor Hard-Wired Post Eye Light Control with Photoelectric Switch, Auto On/Off, ETL Listed, 1 Pack An outdoor lighting photocell sensor is a device that is used to detect changes in ambient light levels and turn on or off the outdoor lights accordingly. These devices are typically used in residential, commercial, and industrial applications. They are designed to help reduce energy consumption and costs associated with outdoor lighting.
