DFRobot Gravity: Analog CO2 Gas Sensor;

Introduction

"Greenhouse Effect" is melting the Earth ice core every minute and creating dangerous icebergs. By knowing the exact concentration of CO2, we can do somehing to reduce the CO2 and to protect our Earth. For that reason, this CO2 sensor is designed by DFRobot engineer. This is the first CO2 sensor in Arduino 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 for stability and reproducibility. Onboard heating circuit brings the best temperature for sensor to function. Internal power boosting to 6V for heating sensor best performance.
This sensor has an onboard conditioning circuit for amplifying output signal.
