Three LED indicators, indicating the surrounding environment.
Indicator Instruction:
When the value is less than 150, the green D2 light turns on, the surrounding environment is relatively healthy;
When the value is greater than 200 and less than 400, the yellow D1 light turns on, the surrounding environment is moderate pollution;
When the value is greater than 400 less than 700, the red D3 light turns on, the surrounding environment is severe pollution;
When the value is greater than 800, all light turns on, the surrounding environment is serious pollution.
