1 INTRODUCTION
1.1 What’s LoRa
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.
1.2 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 configuration).
