You may have seen street lamps with solar panels when you are shopping. This is what we call solar traffic lights. The reason why it can be widely used is mainly because it has the functions of energy saving, environmental protection and electricity storage. What are the basic functions of this solar traffic light? Today’s Xiaobian will introduce you.
1. When the light is turned off during the day, the system is in a sleep state, automatically wakes up on time, measures the ambient brightness and battery voltage, and verifies whether it should enter another state.
2. After dark, the LED brightness of flashing lights, solar energy and solar energy traffic lights changes slowly according to the breathing mode. Like the breathing lamp in the apple notebook, inhale for 1.5 seconds (gradually turning on), exhale for 1.5 seconds (gradually turning off), stop, and then inhale and exhale.
3. Automatically monitor the voltage of lithium battery. When it is lower than 3.5V, it will enter a power shortage state, the system will sleep, and wake up regularly to monitor whether it can be charged.
4. In the environment where solar energy and solar energy traffic lights are short of power, if there is sunshine, they will be automatically charged.
