How to use MG811 Sensors Arduino Forum

20210506· 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).

CO2_Sensor_SKU_SEN0159DFRobot

This is the first CO2 sensor on the opensource hardware 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. Once the CO2 concentration is high enough (voltage is lower than threshold), a digital signal (ON/OFF) will be released.
