@richardst - not so much. The largest cost of electronics in a tandem trailer (commercial) is the copper in the signal wiring. So, in order to minimize that cost the controller is being put in the tandem axle assembly more and more, with pressure sensors to measure the positive air pressure in the airbrake lines.
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.
