For that reason, an HQ CO2 sensor is designed by DFRobot engineer. This is the first CO2 sensor in OSHW market. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer on board is designed to set the threshold of voltage. As long as the CO2 concentration is high enough (voltage is lower than the threshold), a digital signal (ON/OFF) will be released.

Product Details

Features:
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.

Specification
Detect range is: 350—10000 ppm
Operating voltage:5V
Interface: Analog
One digital output
Onboard heating circuit
