The process of debugging my remote oil level sensor continues. This is
based on a PICO W plus a nano timer to wake it up every couple of hours
to send a message via the home wifi.
After an issue in which it stayed woke, and flattened its battery and
never sent any data, the code has been modified and its back on the tank
after extensive testing, with three *lithium* batteries.
I was unaware of lithium primary cells in an AA format till now. But
three of these start out at 5,2V and stick around 5V for a long time.
Perfect for the unit.
In addition they are reckoned to be more tolerant of the cold and to
last twice as long.
Early days, but if anyone is thinking of battery powering a PICO outside
for intermittent use, a nano timer and lithium primary cells looks to
be the best technology.
