With a current consumption of only few uA, this thermometer is capable of running for years from single CR2032 (and forever from solar cell)

"Solar 2032" is definitive the next step!
Pherhaps you can compare Coincell CR-2032 3V@225mAh via Solar2032 ?V@?mA
and show more measurements about little light.(Inner rooms and outdoors)
The solar coin cell board is awesome! Nice find on the BPW34s! Very creative, way to go. It has inspired new ideas for some projects!
That coin cell holder form-factor for the solar cell board is brilliant!
Great execution! Kudos on using PIC, its nice to see other PIC people on here. Maybe its a coincidence in this case, but i too tend to try and build al my projects using all Microchip Parts.
Thanks! I use PICs and MCP parts in almost all of my projects.

Dear Miro, I had a idea about multiple layers of solar cells(cr2032)with transparent thin layers.
1. Layer output 100% 3,20V
2. Layer output 15% 0,48V
3. Layer output 5% 0,16V = 3,84V good enough for electronics with memory cards.
