Abstract
A street light system and operation method thereof are provided. The street light system includes a master street light device and a slave street light device. The master street light device includes a first light emitting module, a sensing module, a first microcontroller, and a first driving circuit. The slave street light device includes a second light emitting module, a second microcontroller, and a second driving circuit. The sensing module obtains a temperature, a relative humidity, and a dust concentration. The first microcontroller calculates a light attenuation rate according to the temperature, the relative humidity, and the dust concentration. The first driving circuit drives the first light emitting module according the light attenuation rate. The second microcontroller obtains the light attenuation rate. The second driving circuit drives the second light emitting module according the light attenuation rate.
