The MQ series of gas sensors use a small heater inside with an electro-chemical sensor. They are sensitive for a range of gasses and are used indoors at room temperature.
They can be calibrated more or less but a know concentration of the measured gas or gasses is needed for that.
Chip: LM393, ZYMQ-2 gas sensors
with a signal output instruction.
dual signal output (analog output, and TTL level output)
0~5V analog output voltage, the higher the concentration the higher the voltage.
the gas, natural gas, city gas, smoke better sensitivity.
with a long service life and reliable stability
rapid response and recovery characteristics
Sensitive for Methane, Butane, LPG, smoke.
This sensor is sensitive for flamable and combustible gasses.
