i been to Zhuhai, I think it's just a less crowded and more touristy version of Shenzhen. Don't know about "Riviera of China" though, that's more Hainan I think. (Though Hainan is more often called the Hawaii of China)
Anyways, there is a travelogue of Zhuhai for people going to Honeymoon there, some picture are in the end.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
