MG811 CO2 sensor wiring - Sensors - Arduino Forum

· MG811 CO2 sensor wiring. Hello. I have a CO2 sensor with 4 pins. VCC, DOUT,AOUT, GND. Where does the VCC, AOUT, and DOUT wire to? I found no wiring manual when I purchased this sensor off of ebay. I have gone to this link where someone is using the same sensor. However, I don't follow his path considering the third pin (red) isnt going anywhere.

DIY CO2 Incubator - Arduino and Circuits

· Luckily an Arduino library was developed for this CO2 sensor so I didn't have to do much work to get it up and running. I recommend reading this forum which has the library and some example code (also maintained on github a big shoutout to DirtGambit and Rob Tillaart for developing this). I am currently using the version of the library on page 1 of the forum with no problems.
