The software for the sensorbox will be made available soon. Here are some details:

  • the I2C communication uses the Wire library on the Arduino and the plain Linux C API on the Raspberry Pi. Refs: Arduino's Wire library, Linux I2C API
  • The Web interface to configure the sensorbox uses Apache and PHP. There is a single configuration file that is stored in JSON format.
  • The images of the webcam are taken using Tobias Müller's v4l2grab application.
