Current state of energy harvesting and LoRaWAN
summary
Feasibility data and hard numbers drive the verdict: a Semtech study uses 200 lux 8 hours/day with a 45×45 mm PV cell plus energy conditioning and a Murata 2GT (LR1121) module to send every 90 minutes and still show ~30% energy surplus; Dryad reports the gas/smoke sensor itself consumes ~99% of a node’s energy budget, gateways run a few milliamps average on ultra‑low MCUs, some designs reach ~11 µA average consumption, and 30 companies already join the LoRa Alliance taskforce.
