Gravity: Analog CO2 Gas Sensor For Arduino (MG-811 Sensor) _ARD_SHIELD_RELAY you may need the Romeo

you may need the Romeo (Romeo V2- an Arduino Robot Board (Arduino Leonardo) with Motor Driver)

There is no more need to fear the heat

The pixels are connected by a 4-conductor cable

3 Megapixel serial JPEG still camera module has a compact size

Gravity: Analog CO2 Gas Sensor For Arduino (MG-811 Sensor) _ARD_SHIELD_RELAY you may need the RomeoGreenhouse Effect is melting the Earth ice core every minute and creating dangerous icebergs. By knowing the exact concentration of CO2(Carbon Dioxide), we can do something to reduce the CO2 and to protect our Earth. Here is the Arduino based CO2 sensor designed by DFRobot lovely engineer. This is the first CO2 sensor in the Arduino market. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is
