1 The system realizes the function

• Real-time monitoring ： Real time monitoring of ambient light , The light level of the street lamp and whether it is faulty .
• Manual control mode ： You can control the five levels of brightness of the light according to your own wishes .
• Automatic control mode ： When the ambient light is lower than 30% And when someone or a car passes , The brightness of the light can be automatically adjusted according to the environment of the street lamp , When the ambient light is higher than 30% And when someone or a car passes , Don't turn on the light .
• Fault detection ： When the street lamp breaks down , Buzzer alarm reminder , And put the fault information of the street lamp in APP Last reminder .
• APP Remote monitoring ： Through Bluetooth wireless communication technology and mobile phones APP signal communication , Realize remote information interaction on the mobile phone .
