During out SYSTEMS fair presentation, an idea was born: an external sensor box!

There is an initial discussion (in German):

http://freeyourphone.de/portal_v1/viewtopic.php?f=3&t=661&p=6966#p6966

Contents

Features

  • analog sensors
  • connected as USB (host)
  • battery extender (?)

Sensors

  • Temperature
  • Humidity
  • Barometer
  • magnetic compass
  • Light intensity / Color
  • Laser / Ultrasonic distance
  • Voltmeter (?)

Other proposed extensions

These ideas go beyond the original Sensorbox idea but some of them can be easily added:

  • LED lamp
  • GPS Antenna
  • Battery pack
  • Camera
  • USB Hub
  • RJ45

Mechanics

There is currently some discussion if it should be a Jacket or an external box. http://freeyourphone.de/portal_v1/download/file.php?id=51

Electronics

Software

  • Device is addressed as a simple serial interface over USB
  • allows to switch on/off each sensor (so that power drainage can be controlled)
  • sends every 0.1 seconds a data block with latest data values
  • User-Interface runs on the Freerunner
