can carbon dioxide sensor module yourself

Testing the MH-Z19 Infrared CO2 Sensor Module • Circuits

· All carbon dioxide sensors need calibration. Depending on the application, this can be accomplished by calibrating the sensor to a known gas, or using the automatic baseline calibration (ABC) method. Both have pros and cons you should know. Why Calibrate? The non-dispersive infrared (NDIR) carbon dioxide sensors rely on an infrared light source and detector to measure the number of CO 2 ...

MG811 Carbon dioxide sensor module for CO2

This MG811 sensor module is a little bit special because it require 6VDC to function properly. There is an on-board signal conditioning circuit for amplifying output signal and an on-board heating circuit for heating the sensor. The MG-811 is highly sensitive to CO2 and less sensitive to alcohol and CO. It could be used in air quality control, ferment process, in-door air monitoring ...
