Energy Harvesting (PV) demo
Introduction
A wireless demonstrator powered by harvested energy stored in ceramic batteries.
This demonstrator is built to showcase what is possible with energy harvesting, storage in solid-state batteries, and BLE communication. All this is now a possibility due to the nPZero power-saving IC that reduces power consumption to new levels.
Demo variants
Different versions of the PV demo has been developed, using different key components for energy storage and sensors.
