When you read the data sheet correctly you can see, that the distance between the pins is different for a AA and AAA battery holder. That`s why I was asking if somebody can recommend a holder that fits.
Hey! This looks like a great project! I'm considering building one for my hives.
I notice that the legs need to be welded. That will be a chore for people that want to make this build themselves.
Is this version designed to be built by anyone?
Did you consider using open source or standardized hardware? Think of 2020 alu profiles or something, to allow reasonable buildability for users other than beep-base-shop.
Also let me know if I misjudged, and that all components could be simply bought online.
Stay awesome!

Hi @tbowmo, do you mind to explain a bit about the design? I'm interested with your design.
I will use these steps for removing voltage regulator, http://goo.gl/CsZaNg
So the design will be battery > external step up regulator (http://goo.gl/PFt99R - to stabilize 3.3v) > vcc pin ?
with these then I can use my first post design?
Thanks
@hek The capacitor addition seems to be helping. So far 9 hours and all the values are updating as they should YAY!
I'll continue to monitor but i'm hopeful that this is the solution.

The 85 reading is actually an error message used by the ds18b20 to indicate it has not had time to complete the processing of the reading. Most commonly this is only seen when the node first boots up and can be ignored or fixed by adding a small delay. You will find a lot of information on this if you do a google search. I have never experienced it myself but from other posts on the net it seems power supply problems and long cable runs to the sensor can also cause the error. Some have also had success by using a different resistor value. Note you only need one resistor fitted near your nodemcu not a resistor at each ds18b20.
If the 85 reading is well outside your expected reading you could just filter out any readings over 84 as well.
