How Teams Built Low‑Power IoT Solutions with Huawei LiteOS at the HDG Hackathon

Event Overview

From May 26‑28, Huawei LiteOS organized the “HDG | Huawei LiteOS Hackathon” in Shenzhen’s Seg Co‑Creation Space. Over three days, 200 participants on‑site and 5,500 online witnessed intense competition.

The hackathon’s theme was “Edge‑Cloud Interconnection”. Teams were required to use Huawei LiteOS to collect and process sensor data, register devices, report data to the Huawei OceanConnect IoT cloud platform, and enable remote device management.

Winning Projects

First Prize – MiRui Team: Low‑Power Visual Doorbell integrated a doorbell with a security camera. When the button is pressed or motion is detected, the device wakes from sleep, sends a notification to the homeowner’s phone, and operates for 4‑6 months on a single charge. The board used the HiSilicon HI3518EV200 chip, Huawei LiteOS, and OceanConnect.

Second Prize – Makernet developed a beacon‑based visual crowd‑flow analysis system that captures RSSI signals to build a real‑time distributed hotspot management platform for public spaces.

Second Prize – Intek created a smart air purifier using electro‑water mist technology, controlled via WeChat, with multi‑threaded task handling on LiteOS for higher efficiency.

Third Prize – ZhenNengLiang, Baby Not Cry, Dream Team presented various IoT solutions such as a smart space showcase, an infant sleep monitoring system (iBaby) with temperature, heart‑rate, and posture sensing, and a natural‑gas alarm using GPRS and cloud alerts.

Judges and Remarks

Judges included senior figures from Huawei LiteOS OSDT, the Huawei IoT OceanConnect ecosystem, and the China Software Industry Association. They praised the maturity of the solutions and the high rate of “edge‑cloud” implementation.

Future Activities

The hackathon series will continue in other cities. A LinuxCon workshop in Beijing (June 19‑20) will focus on “Huawei LiteOS Open‑Source Ecosystem Enables NB‑IoT”, and a Huawei Developer Competition is planned for July‑August, emphasizing IoT.
