I once did some work with Stanford Research Systems Model DS345 Synthesized Function Generator. I didn't like their user interface, but the provided the details on controlling the device via an RS232 port. I set up a UI (at least a portion of the UI) in Excel.
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.
