Would this sensor work with a Fibaro binary sensor?

I was wondering, would this sensor work with a Binary sensor?

 

Schabus 200897-SE Gassensor 5 V

If not, are there any other sensor available that can measure ethanol and work withe the Fibaro Binary sensor?

I doubt it. The documentation doesn't contain a schematic and also it says "Der externe Sensor ist geeignet für die Gaswarngeräte GX-A1 und GX-HS und wird über eine JR45 Steckverbindung". To me that translates as "to be used on a GX-A1 or GX-HS alarm device". I had a quick look at the GX-A1 and they mention: "1 integriertes Schaltrelais 5 A (potenzialfreier Wechsler) ermöglicht Anschluss an BUS-System (EIB) oder externe Geräte". So you could connect the GX-A1 to any Fibaro device (using the potenzialfreier Wechsler).

Thank you for your response. Your last sentence confuses me a little

[petergebruers 1,268]

Yes, the UBS works with a "potential free contact". If you wanted a battery operated sensor, the Fibaro Door/Window sensor would work too.

Thanks! I will order one and see if it works

I have orderd this device, but since there is no scheme available: how to connect it to the fibaro binary sensor? The gassensor has a brown, white and green wire.... no clue which is wat

[petergebruers 1,268]

I am confused. The webpage says it connects to the GX-A1 or GX-HS. Surely you have the documentation of those units? I've got the impression that you bought only the sensor, not the alarm unit (see post nr 2), am I correct?

[kariem112 3]

Yes, just the sensor, you are correct

[petergebruers 1,268]

In that case, I don't have a clue. I am really sorry if my post made you believe this sensor was compatible with Fibaro. I've reread my post a few times and I do think that I'm saying that the sensor connects to the alarm system, and that the alarm system is compatible with a binary sensor. I think that is a very expensive solution. I'm not sure what those three wires are. I'll see if I can find anything... but I'm not optimistic.

[petergebruers 1,268]

The colors of th wires are in the manual of the alarm:

They don't say what they are, but an explanation further down the manual suggests it's an analog signal, power and ground but that is far from certain. That kind of signal is not compatible. But the outputs of the alarm system are compatible.

[kariem112 3]

hmm that is a shame. That would leave this thing useless

/emoticons/default_smile.png" alt=":)" srcset="https://forum.fibaro.com/uploads/emoticons/[email protected] 2x" width="20" height="20" />  Do you perhaps know of a sensor that can measure alcohol and can be connected to the Fibaro ? I have seen some alternatives (mainly to connect with arduino) but they all seem analog..

[petergebruers 1,268]

Unless you buy the alarm module, it seems impossible. I think it makes sense to have that unit, so you have a standalone alarm. But it's expensive... I don't particularly look out for that kind of sensor, but I the things I see on banggood, ebay and aliexpress all seem to be analog (for arduino), like you say...

[petergebruers 1,268]

I've bought a module on aliexpress, that might be *adaptable* (to be tested!) to a UBS:

This is the spec of the sensing element:

It can take 4 weeks to arrive. I'll post more information when I've tested it.

In the documentation is a schematic diagram, marked as "fig. 14". If you can build that kind of electronics around it, you can connect the collector of Tr1 to the input of the UBS (and leave out the buzzer circuit C5, C6, B1, D1. The documentation mentions a "socket", but I didn't find a suitable one. That's probably because I'm not trying hard enough. Sockets make sense, because these sensors have a limited lifespan. I've found published data ranging from 2 up to 5 years.

If you're doing that kind of DIY, it might be more interesting to use a RGBW in 0-10V input mode and connect the sensor element between ground and one of the inputs, and use a 7805 or equivalent for the heater of the sensor. The advantage would be that you can set the sensitivity in software. But maybe you don't want the alarm to depend on the HC?

I've not tested this sensor, I find it a little bit pricey, just to do a test. I don't have combustible gases in the house

heheheh well, the documentation I found was quit unreadable to me. I have seen some of schematics, but they dont really make sense (at least to me

/emoticons/default_smile.png" alt=":)" srcset="https://forum.fibaro.com/uploads/emoticons/[email protected] 2x" width="20" height="20" /> ) I just need a sensor that can fire up the binary sensor (or any other way) when the concentration of gas is to high.

I have received a pre made alcohol sensor. When detecting alcohol, it increases the voltage on the output. When nothing is detected, it outputs .40 and the maximum would be around 2 volt on the output:

would I be able to use an rgbw controller and use a energy usage limit to start a scene ?
