OK, so just drop a channel, beef up the audio driver, add an MLC flash array, and put in a single-cell solar charger management function. Kit a mic, speaker, small solar panel and battery, and you get a single chip solar powered garden lamp that plays stored tunes or recorded voice when it hears a specific command or sound (make use of that DSP).
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.
