Internet of Things for Architects

Part 1 – Sensing and power

The internet starts or ends with an event: a simple motion, a temperature change, perhaps an actuator moving on a lock. Unlike many IT devices in existence, IoT in a large part is about a physical action or event. It responds to affect a real-world attribute. Sometimes this involves considerable data being generated from a single sensor, such as auditory sensing for preventative maintenance of machinery. Other times, it's a single bit of data indicating vital health data from a patient. Whatever the case may be, sensing systems have evolved and made use of Moore's law in scaling to sub-nanometer sizes and significantly reduced costs. When one talks about the billions of devices in IoT, this is what they are referring ...
