Check your units and their abbreviations. A second is appreviated s, not S.
Not bad otherwise, but way too brief for my tastes. Should have a lot more explanation about WHY, not just the WHAT. Also I think the last sentence deserves more than a brief mention. One should always try changing the settings, even if you think you know what you are seeking. You often find something you weren't looking for. What if the engineer in this case was looking only for high frequency noise? He could have missed the min/max voltage problem entirely.
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.
