Retro-Fitted LoRaWAN Smoke Detector
A tiny 22×25mm LoRaWAN board designed to be retrofitted to an existing smoke detector, enabling it to send an alarm to a distant communications gateway.
I designed this tiny 22 x 25mm LoRaWAN board to be retrofitted to an existing smoke detector as an add on, enabling it to send an alarm to a distant communications gateway. Demonstrates the kind of minimum footprint achievable.
