How to use MG811 - Sensors - Arduino Forum

· Hi. I got the sensor MG811 that senses carbon dioxide, you can see an image of the sensor here I googled to use that sensor properly but i have doubts about the wiring with arduino and the proper way to calibrating. So, i got think i can got the data from AOUT pin, but i really don't know if i can use the 5V pin from arduino to connect in vdd or i need another source (around 12V). So, what …

Carbon dioxide sensor - Wikipedia

NDIR sensors are most often used for measuring carbon dioxide. The best of these have sensitivities of 20–50 PPM. Typical NDIR sensors cost in the (US) $100 to $1000 range. NDIR CO 2 sensors are also used for dissolved CO 2 for applications such as beverage carbonation, pharmaceutical fermentation and CO 2 sequestration applications.
