MQ2 Reading different gases Sensors Arduino Forum

20210506· MQ2 Reading different gases. Hi all. I am using this code example from Sandbox Electronics to read from the MQ2 gas sensor. However, all my readings are 0. If I use a simple analog reading on the specific pin, I get the expected analog values from 0 to 1023, usual values around 250, and if I expose it to gas for example goes up to 1000.


Grove Gas Sensor(MQ2) Seeed Wiki

The Grove Gas Sensor(MQ2) module is useful for gas leakage detection (home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke or Propane. Due to its high sensitivity and fast response time, measurement can be taken as soon as possible. The sensitivity of the sensor can be adjusted by potentiometer. Note. The sensor value only reflects the approximated trend of gas ...

Carbon Monoxide Sensors: How Do They Differ and Why …

20210528· A CO/H2 low sensor with 5% or less H2 gas crossinterference would display 5 ppm or less of CO if 100 ppm of H2 was present in the environment. The CO/H2 null sensor does its best to completely nullify the effect of H2 on the CO sensor. In practice, a CO/H2 null sensor will typically have 1% or less H2 crossinterference. Going back to the ...

biogaz et co2 Innovalor

Le CO2 se trouvera toujours dans le biogaz du fait que pendant la digestion anaérobie (c''estàdire la dégradation en l''absence d''oxygéne), la matiére organique est décomposée par des bactéries formant un mélange de CO2 et de CH4 avec des traces de H2S et de la vapeur d''eau à la pression de saturation.


Co(H2O)6 2+/ CoCl4 2 Equilibrium Demonstration Sheet

Co(H 2 O) 6 2+ (aq) + 4 Cl(aq) <=> CoCl 4 2(aq) + 6 H 2 O(g) The Co(H 2 O) 6 2+ complex is pink, and the CoCl 4 2 complex is blue. This reaction is endothermic as written, so adding heat causes the equilibrium constant to shift to the right. This, correspondingly, makes the solution blue. When the AgNO 3 is added, Cl is removed from solution. This shifts the equation back to the left, and ...
