How to use MG811 - Sensors - Arduino Forum

06/05/2021· 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).

Kohlendioxid CO2 Sensor (Arduino compatible) -

By knowing the exact concentration of CO2, we can do somehing to reduce the CO2 and to protect our Earth. For that reason, this CO2 sensor is designed by DFRobot engineer. 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 ...

CO2 Monitor - Arduino Project Hub

And where Rs410 is the sensor resistance measured in clean air (410 ppm of CO2) and f_RH_T_410 is the correction factor at the moment that the clean air sensor resistance is measured. Here we assume that the correction factor as a function of relative humidity and temperature is equal for CO2 and hydrogen. I do not have any calibration gasses ...
