Audio modules with digital interfaces are of great demand in the present day electronic products, but CODEC is something different then what is said here. What is discussed here is a Transducer and Digital Interface.
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.
