Autonomous Wireless Sensors

  • Bernhard E. Boser

Abstract

Sensor nodes comprising a power source and means for communication significantly reduce the barrier to sensor deployment and enable a vast array of new applications. Power represents the most significant constraint in many applications. We discuss available power sources and the power dissipation of circuits and optical and RF communication. A solar powered node with passive optical communication has a volume of just 16mm3 and measures ambient light and acceleration. A larger unit fabricated from off-the-shelf parts and RF communication implements a self-configuring network for communicating sensor results.
