Abstract
A colorimetry CO2 ppm level sensor has been developed. Based on an optimized water-based ink, the sensor covers the range of 250 to 1500 ppm, is not affected by common indoor pollutants (NO2, CO, CH2O) and do not show signs of degradation after a week of operation. A calibration method has been proposed to dampen the effects of humidity on sensor prediction. Find out more at the conference.
