ITEM RELATED - Day night switch/day night sensor/light sensor switch/automatic light switch/day night automatic light sensor switch/dark light switch/dark light sensor.
ITEM DETAILS - The image shows a photocell sensor, also known as a photoresistor or light-dependent resistor, which is commonly used in automatic street light switches. This type of sensor automatically turns lights on and off based on the ambient light level. It is widely used for outdoor lighting in places like streets, gardens, parks, and highways. The sensor works by having a high resistance in the dark and a low resistance when light is present, which allows current to flow and activate the light. This technology is energy efficient because it ensures lights are only on when needed.
