Cigaret smoke detector

alowhum Plugin Developer last edited by alowhum
After reading a lot of posts on the forum, I haven't found what I'm looking for.

I would like to detect cigaret smoke, and cigaret smoke only. It shouldn't go off in other situations, like:
- vacume cleaning
- cooking
- gas powered room heater
- Fine dust sensors would detect smoke, but they would also detect those other things. I have experienced this first hand.
- Optical sensors are used in commercial smoke detectors. But they would also detect other particles? I haven't seen the DYP-ME0010 discussed on the forum yet. It doesn't get great reviews though..
- Ionisation detectors are used in commercial smoke detectors. But I cant find those as a separate sensor. I guess I could hack a commercial smoke detector (as others have done on the forum). But ideally I'd like a standardised component.
- Could adding a CO detector work to filter out events that don't involve fire?
So..
- Is there a magical sensor I don't know about that could do this?
- I suspect I probably need some combination to filter out the edge cases. But which combo would give the very best results?

@andriej Hi, I had problem using the main branch mysensors/Raspberry, that because of the bit-field struct (header_s) in Sensor.h They will get packed in different order on the arduino compared to the RPi (at least with my compiler, gcc). In order to fix this I created the 1.4dev branch. It uses full bytes instead of the bit-fields, but you need (of cause) to compile both the sensors (arduino) and the gateway (RPi) using the 1.4dev branch. We need to fix this in the main branch later on (and use the same files as in mysensors/Arduino/libraries/MySensors)

Thers is actually support for pjon as transport in MySensors: https://github.com/mysensors/MySensors/pull/1278 I don’t know how it works though.

it is up and running
That's a fascinating real-world example of AI's power, and it definitely raises important questions about how community forums can evolve to stay relevant alongside these tools.

@ZenBlizzard , yes thanks, thats the point. How to deal with smartSleep() and battery lifetime.

@Tmaster I think it writes better code than a lot of code I've seen, and the documentation is a lot better. The latter, of course, is because most coders don't document. some key elements: good statement of work -- Purpose of the Code is key (did you write that? Good job!). This will guide the AI to write what you want. descriptive variables good documentation code is independent of reading sensors up-to-down/down-to-up I spent a couple hours analyzing, researching and writing and re-writing this and all I can say is that the AI didn't catch is, as far as I can see, if your sensors are too far apart or your magnet is too weak, you could get false readings. You, being the author of AI directive, are responsible for for the code. The AI is just a tool. I started my coding with assembly language, though at that time we still had to enter the binary on some machines (set 16 switches, then press commit). ForTran and COBOL were the first real high level languages and subsequent languages, pascal, c, java, etc. were improvements. AI is a quantum step. It's still coding, but you have to learn how to talk to the AI to get what you want. Good project! Let us know how it turns out and if you had to tweak the code. -OSD
