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

@korttoma UVM-30a still the prefered sensor Cant say. I have been using this for the last year (wrong apparently) but worked as expected. Does connecting a booster to an output pin that is turned of work as expected? Does not the booster try to boost even if the output pin is low? I dont know what will happen over time so I have to come back to that but I had a reading of 5uA in sleep mode which to me indicates a success. I did so because one of the sensors has a minimum of 3.3v and that would stop working pretty soon. Since the rest of the system should be able to go lower I wanted to test... the node is really stable and working great so far!

Hi, this one looks very nice and not shouting "i am a sensor". I am just curious, how long do the batteries last?

Hello fleinze, What about this project? Your sensors still working? I'm trying to build the same but I have some problem to change the efuse value: "I changed the efuse value to 0x07 (BOD off)" I' dont know how to edit the boards.txt file and how to install it in the arduino pro mini. Could you explain the procedure step by step or link me a good complete tutorial ? Thank you very much

@litunbls This forum is Arduino only really... Search the web or convert an Arduino library so it can be compiled in Keil.
