co2 sensor mg811 arduino

: SainSmart MG811 Gas Sensor Module for Arduino ...

Later I bought a A-D power converter and a couple of separable power jack connectors so that I split the 6V supply into the Arduino and the MG811 sensor. Another problem I had was that the signal output is quite low, only about 330 mV at normal atmospheric levels. Zero CO2 concentration would produce an output voltage of about 280 mV.

Gravity: Analog CO2 Gas Sensor | Arduino Official Store

Great and powerful sensor for everyone that wants to know the exact concentration of CO2 (Carbon Dioxide) in the air. This is the first CO2 sensor compatible with Arduino. 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.

CO2 Sensor MG-811 (Arduino compatible) - Botnroll

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.
