CO2 Sensor mg-811 | Archived Forum

25-02-2014 · Re: CO2 Sensor mg-811. Submitted by borpin123 on Fri, 28/02/2014 - 16:05. Bit more research! The Air Quality Egg is not currently available and the airpi does not have a CO2 solution. Acceptable internal CO2 levels it seems, are around the 1000-1500ppm so this device should be able to measure it adequately.

Octopus MG811 CO2 Gas Sensor - elecfreaks.com

Octopus MG811 CO2 Gas Sensor is a CO2 electronic brick in our OCTOPUS series, the basic design for the outlook, PCB fixing holes and connections are the same with them. The higher the CO2 concentration is, the lower the output voltage would be. The users can read the CO2 value easily after checking our brochures and coding samples.

MH-Z19 CO2 sensor | MySensors Forum

23-03-2017 · Loses callibration. It's mostly a chemical proces. The cool thing about the MH-Z14 and the even better MH-Z19 is that they use light spectrum analysis. They send infrared light, and measure how much of that light is absorbed in the spectrum that CO2 absorbs in. …

operational amplifier - Amplifying signal from CO2 Sensor ...

I am trying to amplify a MG811 CO2 sensor to a range readable by an ATMEGA2560 (0-5v). I have other analog sensors, so do not want to change ref voltage on Atmega. I have found a module that scales the signal and want to replicate the circuit from the documentation, but want to make sure that the schematic I have is correct. It seems from the module documentation that the sensor operates in a ...

Mg811 — Parallax Forums

04-04-2012 · I'm using the mg811 co2 sensor to monitor office air, but I have some problems computing the ppm from the output voltage: the data sheet says: EMF = Ec - RT/(2F)*Ln(P(CO2)) where: R = 8.314472 J/(mol K) F = 96485 J T = (i believe that is room temperature) 293.15°K I've measured EMF at 500ppm and 20°C and it results 1.04V thus Ec = 1,12 V.
