Industry WSN System Theory and Typical Architecture
Wireless sensor networks (WSNs) consist of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature,
sound, vibration, pressure, humidity, motion, or pollutants. These sensors cooperatively pass their data through the network to a main location, the base
station. Modern WSNs are bidirectional, enabling users to control the activity of the sensors.
WSNs are built of "nodes," from as little as a few to potentially thousands, with each node connected to one or more sensors. Each such sensor network
node typically has several parts: a radiotransceiver with an internal antenna or connection to an external antenna, a microcontroller, an electronic circuit for
interfacing with the sensors, and an energy source, usually a battery or an embedded form of energy harvesting.
