(I was going to stuff the micro inside, but that is all<br>frozen up tight)..<br><br>Because the micro is only awake for a few seconds every 20 minutes, it will<br>run for weeks off the battery, long after the turkey has thawed.<br><br>The website receiving the post just appends the current local time() and<br>data from the micro processor (humidity, temperature, ADC value) to a log<br>file. The website replies to the micro with the number of minutes that the<br>micro should sleep. No jason, no mqtt, just php and html. Webpage file is<br>attached..

I thought I could use a GPIO as the<br>source voltage for the thermistor, so that I could turn it off when<br>not needed, but it doesn't work yet.
