[ Focus on Chemical Machinery Equipment Network ] Smart street lighting can help cities save money and enhance services and public safety, but there are privacy issues
.
Smart street lights are one of the core elements of smart cities
.
Chemical machinery and equipment network hotspots pay attention to chemical machinery and equipment.
Smart street lights are one of the core elements of smart cities
.
Cities can replace old street lights with more energy-efficient LED bulbs.
They can also use wireless connections to activate street lights’ motion sensors when passers-by are approaching , and can automatically remind city management agencies when they need to replace the bulbs
.
Smart street lights can also enhance public safety through network monitoring and environmental monitoring

Automatic control circuit in street lights, it is a common sensor in intelligent lighting
.
The photosensitive sensor is an ideal electronic sensor that can control the automatic switch of the circuit due to the change of the illuminance at dawn and dark (sunrise, sunset)
.
The photosensitive sensor can automatically control the opening and closing of the LED lighting fixtures according to the weather, time period and region

During the bright day, the power consumption can be reduced by reducing its output power.
Compared with the use of fluorescent lights, a convenience store with an area of 200 square meters can reduce power consumption by up to 53%, and its life span is about 50,000 to 100,000 hours
.
Under normal circumstances, the life of LED lighting fixtures is about 40,000 hours; the color of the light can also be changed in RGB (red, green and blue) colorful ways to make the light more colorful and the atmosphere more active

Its wide range, there are: a photoelectric tube, a photomultiplier tube, photoresistors, phototransistors, solar cells, infrared sensors, ultraviolet sensors, optical fiber type photoelectric sensor, a color sensor, the CCD and CMOS image sensor
.
Mainly used in solar lawn lights, light control night lights, cameras, monitors, light control toys, sound and light control switches, cameras, anti-theft wallets, light control music boxes, birthday music candles, music cups, human body induction lights, human body induction switches And other electronic products light automatic control field

.
The light sensor is one of the sensors with the largest output and the most widely used at present, and it occupies a very important position in automatic control and non-electrical measurement technology
.
A simple photosensitive sensor is a photosensitive resistor, and when a photon hits the junction, an electric current is generated

.
The photosensitive sensor is a sensor that uses a photosensitive element to convert a light signal into an electrical signal.
Its sensitive wavelength is near the wavelength of visible light, including infrared wavelengths and ultraviolet wavelengths
.
The light sensor is not only limited to the detection of light, it can also be used as a detection element to form other sensors to detect many non-electric quantities, as long as these non-electric quantities are converted into changes in light signals
