You are correct, the use of barometric pressure sensors to determine altitude is well known, but making one cheap and low power enough for mobile devices what all the MEMS makers are aiming for, and this is one that is gaining design wins in that space. Thanks.
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.
