@Martin--so if you had a measurement system and you changed the gain via the DIP switch, did you think it necessary to recalibrate or at least measure something you considered a known? Switches can fail, you can set them wrong, they can add noise, etc.
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.
