Gravity: Arduino CO2 Gas Sensor
50 units available with a short lead time.
The Gravity CO2 Gas Sensor uses an MG-811 electrochemical sensing element to detect carbon dioxide concentration in the air. The output voltage decreases as CO2 concentration increases, and an onboard potentiometer lets you set a threshold for a digital on/off signal output.
An onboard heating circuit with internal voltage boosting to 6V ensures the sensor operates at its optimal temperature. The Gravity analog interface allows plug-and-play connection to compatible Arduino expansion shields. Note that this is an electrochemical sensor suited to qualitative CO2 analysis — for quantitative measurement, consider an infrared CO2 sensor.
