Micaz and TelosB Micaz and TelosB Presentation Transcript

  • Design Project Presentation By: K. Deepak Raj 2011A8PS348G
  • AGENDA  Introduction  MicaZ  Hardware Components  Software Components  TelosB  Specifications  MicaZ vs. TelosB
  • Introduction  A sensor network contains many sensor nodes.  A sensor node contains microcontroller, transceiver, external memory, power source and one or more sensors.  Motes are building blocks of Wireless Sensor Networks.  The most popular motes are:  Mica2  MicaZ  TelosB
  • MicaZ
