[VicPiMakers Projects] Projects Digest, Vol 6, Issue 5

Fri Dec 18 00:35:22 EST 2020

Can someone help me out here.  Maybe it is not as interesting as I
thought.  Basically, I learned how to deep sleep a battery powered ESP32.
The turkey was unimportant.  A very portable device that reports
humidity (a cause of mold, for instance, or of hugely expensive water leaks
in a condo) and temperature (for cooking, etc) should be in everybody's
house, IMHO.  The turkey stuffed with micros was a bit of a joke.

Deid, I like the bead thermistor more than DS18B20s because, waterproofed,
I can insert it deep into the turkey breast,  for just the right safe
temperature without overcooking.  Besides, I've got 40 thermistors left
<haha>.  They worked fine when powered by 3.3v and not a GPIO pin.  I
suppose I could spare 0.15ma (3v / 20k ohm) continuous drain on the 2600
ma-hour battery.
