All intelligent thermostats, factory sensors, and soil probes depend on an IoT network in order to send their readings to a useful destination. Otherwise, the readings stay stuck on the chip. This guide explains how everything fits together by going over the various layers, protocols, and gateways that connect them. You'll find out how to carry out the tests yourself on your own bench. What Is an IoT Network and How Does It Connect Devices? An IoT network consists of a number of physical objects that sense information, send it, and take action via common connections. Sensors take the measurements, radios transmit the readings, and a remote server stores and analyzes them. It all seems simple. Yet every decision you make affects the range, battery life, and cost. The scale is enormous. Stat ...
