MG811 Carbon Dioxide Sensor

Description:
A gas sensor measures the concentration of gas in its vicinity through direct interaction with the gas. The sensor identifies gases by measuring the current discharge in the device.
MG-811 Carbon Dioxide Sensor, that is a Metal Oxide Sensor, must heat the tank to the specified level. It will cause heat vapor and separate CO2 from the air. This sensor module has an MG-811 onboard as the sensor component. 
Measuring carbon dioxide is important in monitoring indoor air quality, the function of the lungs in the form of a capnograph device, and many industrial processes.
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 application. The output voltage of the module falls as the concentration of the CO2 increases.
This Sensor features good sensitivity and selectivity to CO2, low humidity and temperature dependency and long stability and repeatability. 
The MG811 sensor module is a little bit special because it requires 6VDC to function properly.
It can be used for HVAC applications to monitor the quality of air, monitor fermentation, aerobic respiration, photosynthesis, and other carbon dioxide consuming or producing processes.
