Presentation of an autonomous LoRa device supplied by Energy Harvesting
summary
e-peas demonstrates an AEM Ambient Energy Manager and a LoRa demo kit powered by an indoor photovoltaic cell at ~300 lux sending messages every six minutes the build uses a supercapacitor ~1.1 F sized for ~16 hours autonomy stores ~3.6 J (≈5.5 J per day) the AM cold starts and then boosts from millivolt levels with an internal boost working down to ~50 mV and claims 400 nA leakage the demo shows harvested energy charging each morning and sustained 24/7 sensing and LoRa uplinks without batteries
