Yes the device will be used to record multiple temperatures using DS18B20 sensors on one wire with a single 4.7k resistor. I hooked up 5 and can read them indiviudally since they have there own addresses. I only need the temperature to the nearest degree so they are fine for my purposes.
I actually use a 3.5mm jack and bought a few connectors as like you found that many do not fit, however the very small SMD mounted ones just fit in the standard case. The ones I found are on Amazon:
Glad to hear our issue is cleared.... its understandable for anyone if one has had issues with something in the past to be sensitive - even more so when digital rights are involved as this can quickly become a serious matter.
I think I have some similar views to yours in that area.
OK well all the best with your work..... I stay tuned ! Jimi
