sensors - MG811 CO2 wiring help Arduino - Stack Overflow

20/03/2014· Pay attention that arduino can read at max AREF volt, by default AREF = AVCC = VCC = 5V (please note, taht is vcc of arduino, not of the sensor) DOUT -> digitalOut, goes to a pin depending on protocol used, because it is one wire, it can be something like "OneWire", Voltage and current needed by VCC, and voltage/current ouputted by AOUT and protocol used by DOUT can be extrapolated only …

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).
