Ultra-early detection of wildfires using gas sensors and LoRaWAN
summary
System claims detects fires within 60 minutes using a network of $50 solar gas sensors nailed three meters to trees that measure CO2 CO VOCs temperature and pressure with onboard ML to reduce false positives. A proprietary mesh LoRaWAN multi-hop gateways design links up to 100 sensors per gateway, one sensor per hectare recommended, 26 deployments including pilots with Cal Fire and PG E, 15‑year lifetime, and satellite (Swarm/SpaceX) backhaul for off-grid alerts.
