@Eko-Febrian not sure I understand the question but the gas sensor example might be what you are looking for.

Long time no see... I had time to work on my sensors lately and here are some pictures of my humidity sensor which is running here for three months now: I left out the power regulator shown above and also desoldered the LED and voltage regulator of the Arduino to safe power. The sensor is directly powered by 3.7V of the lithium battery. The voltage is measured and the battery will be recharged when it goes down. Since I also built a 3D printer lately, I was able to put the sensor into a little box. Now I can easily measure humidity and temperature in my bath room and see it in fhem on a raspberry. Currently I'm working on my next pcb... I will show the next one when I'm finished in a new thread.

@epierre thanks. I do have 4 pins, and im using the analog one. I noticed the increasing value you mentioned. I tried to get raw and got a value, but when taking into the mic, the value doesn't appear to change. Does yours?

No, youre right, that wouldnt work for battery powered. I chop the ends off old cell phone chargers and try to keep a room's sensors down to a single box. The only one I've considered being battery powered is the "Mailbox opened" one but thats another project. The polling is really just to allow getting realtime data when you want it. If I think about it more, Ill probably leave it out. I was just thinking out loud near the end.

Never heard of such a thing. Photo detectors could be used to sense the presence of opaque or reflective plastics. There's also colour detectors that could be used if the plastic material have a specific colour. But I guess you would see a few false positives.

ok, some news here: first of all I fixed my issue with the gateway disabling the debug as suggested here. I had anyway some messages lost. Looking at the mqtt broker I couldn't see any message telling me the gw was rebooting and not only messages from gw to sensor were lost also between sensor and gw. I tried to remove the decoupling capacitor and is everything working. thank you
