Arduino + CO2 sensor MG811 - Interfacing - Arduino Forum

· I have been working on setting up my MG811 for a few days. So far pretty good. 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 ...

: SainSmart MG811 Gas Sensor Module for Arduino ...

To get any accuracy out of the Arduino, the signal has to be amplified to get several volts into an Arduino analog input. I tried an AD620AN instrumentation amplifier, but couldn't get it to work. Then I tried an LM358 op-amp and wired it up as a differential amplifier. It worked ok with a potentiometer posing as the MG811. However, when I plugged the MG811 in, the signal wandered up and down ...

CO2 Sensor Calibration: What You Need to Know |

The most accurate method of CO2 sensor calibration is to expose it to a known gas (typically 100% nitrogen) in order to duplicate the conditions under which the sensor was originally calibrated at the factory. ISO certification is available on our high-end sensors to verify this process for medical, research or scientific purposes. Nitrogen calibration is also required if CO2 levels between 0 ...

Finding the Best TVOC Sensor: BME680 vs CCS811 vs SGP30

· Unlike the CCS811 they do provide an accuracy spec of 15%. Do what you want with that number. Cost/Availability. The cost for this part is just about the same compared to the CCS811. Yea, there’s tons more stock! (When you get more than 100 pieces they all equalize to about the same value.) Overall Pros. From a firmware perspective it’s almost as easy as the CCS811. From the test data ...
