The Crikey activity - available at - is a modified version of Sugar's default Measure activity.

The most significant changes are:

  • Activity starts in sensor-reading mode
  • Input is slowed down to 100th the speed, so you can view changes to a sensor's input over a few seconds, instead of a fraction of a second. (A sensor reader, not an oscilloscope)
  • Input is scaled to fit inside the graph window
  • Input is inverted so that temperature and light sensors' input is more intuitive (higher values on the graph from greater temperature and light)
  • You can record and/or set an audio alarm for when the sensor's value reaches the maximum or minimum
