A wireless sensor network is used for the detection of some parameter like temperature change, fire detection, and many more applications. For the accomplishment of this task, the network uses a number of sensor nodes to sense the desired property. These nodes are deployed in area of interest. This paper firstly discuss a basic overview of a wireless sensor network and give brief description of a sensor node and its components. This paper also presents an overview of number of sensors that are used by wireless sensor networks. The classification of sensors is done on the basis of their area of application. A brief summarization is also presented in tabular form covering different types of sensors, their principle for the operation and application areas where they can be used. Since each requirement need different sensor to be used so we can use them accordingly.

My current area of research is Information Security and Wireless Sensor Networks.


Acoustic sensors, Biosensors, Thermal Sensors, Sensor Node

Wireless Sensor Network is of great use now a days because of its wireless and data centric property. We do not need any wires for connecting devices. These networks are used to measure some physical property like pressure, humidity, fire, temperature and many more. The task of measuring is done with the help of a sensor. Sensor is nothing but a transducer that convert one form of energy into other form that is understandable. Sensors can be classified in a number of ways. On the basis of applications, sensor device can be divided as biosensors, thermal sensors, acoustic sensors etc.
