Working, design issues and applications of wireless sensor network

Wireless sensor networks (WSN) also known as wireless sensor and actuator networks (WSAN). These are distributed autonomous sensors for monitoring environmental or physical conditions, like sound, temperature pressure, etc. and used for passing their data via the network to a main location. These are measurement tools which are equipped with transmitters for converting the signals into a radio transmission from process control instruments. Receiver interprets the radio signal after that converts the wireless signal to a desired or specific output, like a data or Analog current analysis via computer software.
