           0-40(green light) represent low volatile gases

           41-70(yellow light) represent moderate volatile gases

           71-99(red light) represent high volatile gases

4, VOC(volatile organic compound):

    Quality display light show red will alarm, remind users that air has reached the level of pollution, suggesting users open the window to take a breath or leave the room harmful gas: 0-99

            0-30(green light) represent harmful gases
