A wireless sensor network is a group of specialized transducers with a communications infrastructure for monitoring and recording
conditions at diverse locations. Commonly monitored parameters are temperature, humidity, pressure, wind direction and speed, illumination intensity,
vibration intensity, sound intensity, power-line voltage, chemical concentrations, pollutant levels and vital body functions.A sensor network consists
of multiple detection stations called sensor nodes, each of which is small, lightweight and portable.Every sensor node is equipped with a transducer,
microcomputer, transceiver and power source. The transducer generates electrical signals based on sensed physical effects and phenomena.
The microcomputer processes and stores the sensor output. The transceiver receives commands from a central computer and transmits data to that computer. The power for each sensor node is derived from a battery.
Potential applications of sensor networks include:
