the sensor. (The concentration output is low, or the sensor can not work normally.) During the zero point calibration procedure by manual, the sensor must work in stable gas environment (400ppm) for over 20 minutes. Connect the HD pin to low level (0V) for over 7 seconds. Zhengzhou Winsen Electronics Technology Co., Ltd
Jul 11, 2017· Instead of calibrating at 0ppm CO2 (nitrogen), the sensor is calibrated at 400ppm CO 2 (outdoor air is actually very close to 400ppm), then 400 ppm is subtracted from the newly calculated offset value. Fresh air calibration is best for sensors in manufacturing settings or greenhouses where the sensor is constantly exposed to different CO 2 levels.
