COTS Dust - RF Motes

  • Atmel Microprocessor

  • RF Monolithics transceiver

    • 916MHz, ~20m range, 4800 bps

  • 1 week fully active, 2 yr @1%


COTS Dust - Distributed Algorithms

  • 1”, $100 Sensor nodes are easy

  • algorithms?


COTS Dust - Optical Motes

Laser mote

  • 650nm laser pointer

  • 2 day life full duty

CCR mote

  • 4 corner cubes

  • 40% hemisphere


CCR Interrogator


Video Semaphore Decoding

2D beam scanning


6-bit DAC Driving Scanning Mirror

  • Open loop control

  • Insensitive to disturbance

  • Potentially low power


~8mm3 laser scanner

Two 4-bit mechanical DACs control mirror scan angles.

~6 degrees azimuth, 3 elevation


Power and Energy

  • Sources

    • Solar cells

    • Combustion/Thermopiles

  • Storage

    • Batteries ~1 J/mm3

    • Capacitors ~1 mJ/mm3

  • Usage

    • Digital control: nJ/instruction

    • Analog circuitry: nJ/sample
