It’s Just a Sensor, Right? The Hidden Complexity Behind Deploy-and-Rely IoT Devices
summary
Ezurio ships the RS26x dual‑protocol (LoRaWAN + Bluetooth) environmental sensor built around RM126x and Lyra24 modules, a CR123A battery, and a Canvas Python application layer; design choices trade antenna placement, thermal mass, and battery size to meet EN12830’s 20°C in 20 minutes response spec and global RF approvals. Field failures (ketchup‑clogged ingress) force enclosure reworks; module reuse and pre‑certified RF stacks cut certification time, and third‑party testing proves which batteries actually survive the temperatures.
