💬 Gas Sensor


  • Admin

    This thread contains comments for the article "Gas Sensor" posted on MySensors.org.



  • Just a note for any Domoticz users who may try this sketch - it presents in the log, but is not available under 'Devices' to be added UNTIL it gets a reading > 0. My solution to that was to go put the node over the gas hob and let the gas run (unlit) for a few seconds so that it generated a reading :-D

    Remember kids, gas is dangerous, stay safe.

    Have you looked at aliexpress?



  • HI Gohan,

    Yes I did, seems that they are very expensive wherever I look. I'll wait on this one ofr now.

    Thanks for the suggestion though :)

    I believe it is on the cheap side. These price ranges are mainly for hobbyist sensor. The real calibrated ones are usually way more expensive. The cheap ones are only good to measure trends, not for the actual value.
