Use heat shrink tube (2mm) over the wires to prevent shorting - keep leads short distance to about 6 inches long between pcb and temperature chip. then hot glue chip to inside of case

Hello Robert,
i modify my PCB and add the DS18B20 to D2.
The App shows 27°C for the PCB-Temp but the Oled shows 11011.
Have you an Idea?
Thanks for help.

PS. Have you had time to think about the Filterwheel Project? ;-)

Hello Robert,
after update to v3 3.25 the OLed shows 1000100% ( or so) for the Humidity.
The Windows-App shows correct 30%.
A solution for me?
I have an old PCB (make from Schematic V3.07), now i have a new Temp 4 (onboard?) on the OLed, can i modify my PCB to connect the new Temp-Sensor?
Thanks for help.
Best Regards
Andreas

try this
Yes.
BS18B20
Sig - Wire to Arduino D2 and a 4.7K resistor - other end of 4.7K to 5V
Gnd - wire to Gnd
Vcc - wire to 5V
Get a DS18B20 in TO92 package. Such as

Hi Robert,
the V326 is OK, OLED shows the correct Humidity now.
I order a DS18B20 and will modify my PCB.
Thanks for help!

This should fix it.
Send me an email to my yahoo account (brown_rb) and I will send you what I have. How is your programming knowledge?

Hello Robert,
my skill in programming is not so good....
I found this two Filterwheel´s
https://www.thingiverse.com/thing:2757513
and
https://www.thingiverse.com/thing:2023405
The last one has an Arduino and Ascon Driver, can i use this for both wheels?
(If you had time and desire to do that)
I test the Dew-Controller V327 Version this evening.
Andreas
edit
The V327 works!
And a other Wheel:
