LoRa (short for long range) is a spread spectrum modulation technique derived from chirp spread
spectrum (CSS) technology. Semtech's LoRa devices and wireless radio frequency technology is a long
range, low power wireless platform that has become the de facto technology for Internet of Things (IoT)
networks worldwide.
1 INTRODUCTION
1.1 What's LoRa
1.2 About Custos WWD
Custos Wireless Water Detector “Custos WWD” detects Water Leakage with long battery operation
lifespan, super tiny form factor detects water from either in body detection probe on 4 sides as well as
optional remote wired water detection probe. It is a perfect companion for Custos BVS to work in concerto
as a complete solution to close water valve once WWD detected water leak (need proper set up on App or
gateway conguration).
