How to use MG811 Sensors Arduino Forum

Jun 12, 2016· May 06, 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).

Gerbil: The Open Upgrade for Your K40 Laser

After experimenting with a stock Arduino UNO R3, I decided that I needed a better Arduino with at least one additional 16 bits PWM channel without an added price tag. Since I am controlling a CO2 laser, speed or additional processing power are not a requirement since the CO2 gas needs time to ionize and quality engraving takes time.
