Any Explosive Gas / Natural Gas Sensor for Z-Wave

Community Playground General Discussions

Hi. I have a gas stove that sometimes gets left on by people who use it and the gas fills the entire house sometimes before anyone notices it. I’m surprised that I can’t seem to find any z-wave solutions for this like there are for co2 or smoke. Anyone know of any solutions?

I don’t know if there is a specific zwave sensor for this gas , if there isn’t there is always the option to make one yourself.

Find a non-zwave sensor which fullfils your requirements. Get for example a fibaro universal sensor, hook it up on your non-zwave sensor and you’re done.
Second option for the zwave part is to use “myensors” with arduino.

They are planning to start shortly a crowfunding campaign.

Thanks for the responses. The universal sensor seems like a good idea as an immediate solution. They only seem to be available in the UK though. Is there something in America that would work the same way? searching universal sensor in Amazon is not bringing up anything promising.

However, the concept seems really sound.

Here is a explosive gas detector that looks reputable on amazon…

I imagine then that I would have to open it up to connect the two devices. How do I know that it has an output? Do all sensors have some kind of output? I tried looking at the manual for the device but it doesn’t mention anything about it.

I think other manufacturers make something similar as the fibaro universal sensor , if you can’t buy the fibaro in the US… Someone else hopefully knows.

For the sensor in the link, you do need an “output” on the sensor , so you can hook it up on the zwave device , not sure if the sensor in your link has it , if not you will have to tinker a bit , hardwire the speaker to the zwave sensor . For a how to , someone wrote about this in a smoke-fire- sensor thread on this forum.

Another approach is to recognise the sound signature of the siren.

I don’t know if this type of device exist. I’ve found just this: http://www.philio-tech.com/pdf/PAT01.pdf

Cor, I have been searching around the forums and have been unable to find that thread. I’m sorry for the trouble, but would you mind posting a link for me. I very well may have to go that route, because the gas sensor I’ve been looking at don’t seem to have any outputs.

Here is the post that I had read a time ago (in French) : AudioMote un périphérique multi-capteurs toujours à l'écoute de votre foyer

Perhaps someone knows an equivalent device ?
