-Ultra low power thermometer with an average current consumption of only ~3uA
-PIC16LF19175 & MCP9700A & MCP1501(-10 or -20)
-1 measurement per second
-Range: -40 - 52°C (with 1,024V reference) or -40 - 125°C (with 2,048V reference)
-Can be powered by a CR2032 or experimental "solar 2032" - 10 BPW34 connected in series without DC-DC converter
-MCU is in sleep mode for most of the time
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.
