Building Smart Farms with Edge Computing Systems Using Kubernetes

summary
A tiny Kubernetes distro (k3s) runs on a Raspberry Pi ARM cluster at the edge to collect LoRa sensor data, process it locally and push only needed results to the cloud. LoRa nodes send HT11 temperature/humidity to a receiver that POSTS JSON to a k3s service; the service records metrics into MySQL, Grafana refreshes ~every 5s, and metalLB provides local load balancing. A live demo showed an ice-bag test with real-time temperature drops visible in Grafana.
