Q: What type of sensors are used in road street lights?

In street lighting systems , commonly used sensor types include photocells (Photocell) and microwave sensors (Microwave Sensor). Photocells, also known as light-controlled sensors or photoresistors, can sense the intensity of light and automatically control the switch of street lights according to changes in light. Keep the lights off during the day when there is plenty of light and turn them on at night when the light is low. A microwave sensor is a motion sensor based on microwave radio frequency technology. It detects objects or human motion in the surrounding environment by sending out microwave signals and receiving the echoes. When people or vehicles pass by the street light area , the microwave sensor will detect the motion signal and trigger the street light to turn on. Sensors automatically turn off street lights to save energy when there is no motion activity.

Question 1

What is a photocell for street lights?

Accepted Answer

Photocells are semiconductors that are light detectors. They are essentially light-dependent resistors because their output is proportional to the amount of light falling on them. Photocells for street lights, also known as light control sensors or photoresistors, are devices used to control street lighting.
Photocells are usually installed on the poles or top of street lights, which are exposed to the outdoor environment. Its working principle is based on the property of a photoresistor, whose resistance value changes when light hits the surface of the photocell. During the day or when there is sufficient light, the resistance of the photocell is low, and an electrical signal to the control circuit causes the street light to turn off or remain off. In the case of night or insufficient light, the resistance of the photocell increases, and the electrical signal will trigger the control circuit to turn on or keep the street light on.

Question 2

What type of sensors are used in road street lights?

Accepted Answer

In street lighting systems, commonly used sensor types include photocells (Photocell) and microwave sensors (Microwave Sensor).

Photocells, also known as light-controlled sensors or photoresistors, can sense the intensity of light and automatically control the switch of street lights according to changes in light.

When people or vehicles pass by the street light area, the microwave sensor will detect the motion signal and trigger the street light to turn on. Sensors automatically turn off street lights to save energy when there is no motion activity.

Question 3

What's the price of photocell for street light?

Accepted Answer

The price of photocell for street lights depends on various factors such as brand, quality, features and quantity you want to buy. Generally speaking, its price is between 5-8 dollars.
