analogread - SainSmart CO2 sensor module use? - Arduino ...

2. I purchased this CO2 sensor a while back: SainSmart MG811 Gas CO2 Carbon Dioxide Sensor Module Sensor Module for Arduino UNO R3 Raspberry Pi. The module has four pins, Vin, GND, Dout and Aout. I assume Dout and Aout are digital output and analog output, respectively. Other than that, the sensor came with no datasheet, instructions, or tutorial.

sensors - MG811 CO2 wiring help Arduino - Stack Overflow

Mar 20, 2014· 1 Answer1. Active Oldest Votes. 2. GND -> negative. VCC -> positive (voltage/current depends on sensor) AOUT -> analogOut, goes to a analogInput if you want to read the sensor that way. 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 ...

MG-811 CO2 sensor | Espruino

Oct 16, 2015· So can't map it like in arduino style way eg. float co2 = analogRead(A0); float ppm = map(co2,0,1023,400,10000); and get readings like when blow ppm rise, when stop ppm drop sensor measure CO2 concentration from 400ppm to 10000ppm - like datasheet said in this range it will change voltage output at very small range (30mV) would like to run it ...

SainSmart MG811 Carbon Dioxide Gas CO2 Sensor

Aug 04, 2014· SainSmart MG811 Carbon Dioxide Gas CO2 Sensor. The MG811 in the name refers to the actual sensor itself which uses a heater inside of an electro-chemical sensor. This sensor must be primed (turned-on) for about 24-36 hours before actually being able to use the sensor. Also, it takes a few minutes for the heating mechanism to reach full potential.
