The fantasy of the IoT ( writes Maxim’s Kris Ardis, Director of Energy Solutions ) is quite grand: everything on the planet can be smart and communicate. The idea is both powerful and impractical. What if every moving part in your car could monitor itself and offer you truly predictive maintenance? That is a powerful vision. What if every brick in my house could communicate its location to my cell phone? It would certainly tell me whether bricks had fallen off the house, but is this a practical use of technology?
The fantasy of IoT tells us that millions of "intelligent" devices should be connected and talking, controlling the world around us. Yes, the falling brick could call the local mason for repair and tell the HVAC to turn up the heat. But this IoT application is not likely to be implemented in our lifetime. Why?
The IoT is only enabled because of two things: the ability of networks to reach countless nodes, and the availability of cost-effective embedded processors to attach to a multitude of devices. This note talks about both; read it at; www.maximintegrated.com/app-notes/index.mvp/id/5725
