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).

Measure CO2 & TVOC using CCS811 Gas Sensor & Arduino

2021-02-08· In this tutorial, we will interface CO2 & TVOC Gas Sensor CCS811 with Arduino & measure CO2 & TVOC in the air. The CCS811 Air Quality Breakout Board is a digital gas sensor capable of sensing a wide range of Total Volatile Organic Compounds (TVOC) & equivalent carbon dioxide (eCO2) with metal oxide (MOX) levels. We can thus use this sensor to identify the air quality …

Arduino + CO2 sensor MG811 - Interfacing - Arduino Forum

2021-05-06· Yes, you do need 6V to run the heater in the Co2 sensor, the arduino will not supply this so you must get the sensor it's own voltage regulator. I have the circuit set up and it works perfect. I just need to code and calibrate. Here soon in the next few days I'm going to set up a page on I'll come back and post a link when it's finished.

CO2 Sensor Arduino Compatible - RobotShop

The CO2 Sensor Arduino Compatible is the first CO2 sensor in OSHW 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 concentration is high enough (voltage is lower than threshold), a digital signal (ON/OFF) will be released. It has MG-811 sensor …
