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.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
