Sensors: Convergence

Sensors have been around since the industrial revolution. The Wireless Sensor Network (WSN) is a technology to make individual sensors smart and self-sufficient. In WSN, the basic constituents are the motes or sensor node consisting of a wireless transceiver, a small CPU and array of sensors. These components are packaged into a single device called Wireless Sensor Node.

The sensor detects and records the ambient parameters of the given environment. The CPU extracts information from the sensed data, executes control instructions and works as a router, following which the communication units send this information to the base station.

In essence, it provides a platform for the integration of entities, living or non-living by means of sensing the physical ambience, comprehending it with in-built intelligence and communicating it wirelessly. WSN is unique, in that, it connects the physical system to the IT infrastructure which is otherwise impossible to achieve.
