CO2 Sensor (Arduino Compatible)

The "Greenhouse Effect" is melting icebergs every minute. By knowing the exact concentration of CO2, we can do something to reduce the CO2 and to protect our earth. For that reason, a CO2 gas sensor was designed by a DFRobot engineer. This is the first CO2 sensor in the OSHW market. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is designed to set the threshold of voltage. As long as the CO2 concentration is high enough (voltage is lower than threshold), a digital signal (ON/OFF) will be released.
  • 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 industrial quality which means stability and reproducibility.
  • Onboard heating circuit brings the best temperature for sensor to function. 5V power input will be boosted to 6V for heating.
  • This sensor has an onboard conditioning circuit for amplifying output signal.
