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. Most of our CO2 products use non-dispersive infrared (NDIR) carbon dioxide sensors.
MH-Z19B NDIR infrared gas module is a common type, small size sensor, using non-dispersive infrared (NDIR) principle to detect the existence of CO 2 in the air, with good selectivity, non-oxygen dependent and long life. Built-in temperature compensation; and it has UART output and PWM output.
These NDIR CO2 sensors measure temperature, relative humidity and CO2. Carbon dioxide or CO2 is a result of human metabolism. Moderate to high levels of CO2 can cause headaches and fatigue. To prevent or reduce high concentrations of carbon dioxide in a building or room, fresh air should be supplied to the room.
