1. Introduction

The Dragino LWL02 is a

LoRaWAN Water

indicates a water leak event and uplink to IoT server via LoRaWAN network.

LWL02 is powered by

2 x AAA batteries

~ 70,000 uplink packets, which result in 2 ~ 10 years battery life. After battery running out, user can easily open the

enclosure and replace with 2 common AAA batteries.

The LWL02 will send periodically data every day as well as for each water leak event. It also

leak times

calculate last water leak

and

instead, device can count each event and uplink periodically.

Each LWL02 is

pre-load with a set of unique keys

server and it will auto connect after power on.
