The single pixel wifi camera is built from a directional antenna made of wasabe pea cans, which have the perfect diameter to act as a highly directional wave guide antenna for Wifi radio waves, which have a wavelength of 12.5 cm.
This directional antenna is moved around by two motors to cover a view step by step, like a single pixel camera, from pixel to pixel. Our customized wifi router is registering the various network names and signal strengths at each given point, and stores this into log files. We load these log files into custom made visualizations software and look for patterns and information in this data.
