For even more immunity on analog signals use a low impedance interface like 4-20 mA. The input to a 4-20 mA receiver is typically terminated with a resistor between 50 to 500 Ohms. It takes one heck of a strong RF signal to have any noticable effect on a 50 ohm terminated input.
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.
