Co2 sensor connexion and calibration | MySensors Forum

I am trying to make my co2 sensor module work. The CO2 module can be found at the following link: ... Now I am struggling to find the value of EMF at 350 ppm CO2. I connected my sensor module to Vcc=5V and to ground . Then i tried to measure Aout. Everytime I connect the sensor it gives a different value! Shouldn't this be constant since the air contains the same CO2 concentration ? In the ...

How To Use MQ-135 Gas Sensor - Codrey Electronics

· Remember, the MQ-135 gas sensor is suitable for detecting (or measuring) of NH3, NOx, alcohol, Benzene, smoke, CO2, etc. If you’ve made it to this point, well done! Now you can add an annunciator of your choice at the output of the module through a suitable driver circuitry. A driver circuit is very crucial here because sink current (Isink) of the LM393 IC is just about 20mA. According to ...

How does an NDIR CO2 Sensor Work? |

These sensors solved the size problem by using folded optics and metalized molded plastic to reflect the light through a curved shape (referred to as a 'waveguide') that was longer than the footprint of the sensor module. The highly reflective coating ensured that the CO2 molecules inside the gas sample chamber would absorb the same amount of light as traditional straight-path design.
