It has MG-811 sensor module onboard which is highly sensitive to CO2 and less sensitive to alcohol and CO, Low humidity & temperature dependency. All components have an industrial quality which means stability and reproducibility.
Onboard heating circuit brings the best temperature for the sensor to function. 5V power input will be boosted to 6V for heating.
This sensor has an onboard conditioning circuit for the amplifying output signal.
NOTE: 7~12V is necessary to power the microcontroller when using the CO2 Sensor to provide an enough current.
Detect range is: 350—10000 ppm
One digital output
