how arduino co2 sensor works

DIY CO2 Incubator - Arduino and Circuits

2014-12-14· 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.

How to use MG811 - Sensors - Arduino Forum

2021-05-06· 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).
