pHloat has the option to be made from several recycled materials including but not limited to, styrofoam, paper, and plastic food containers. If these materials cannot be found they can be purchased along with the necessary electrical components for approximately $25. pHloat functions through the modification of a simple garden moisture and pH sensor that can be purchased at any home improvement store. It acts as both an environmental measurement tool and a floating sculpture, borrowing inspiration from Japanese floating paper. As the pHloat navigates down a stream it is taking a constant pH reading that is being translated by the arduino to produce a variation of colored light (produced by a low energy and cost superbright RGB LED). The different colors of light indicate the level of acidity in the body of water. For example, a normal pH reading would result in the emission of green light while a high pH reading would result in the emission of red light. Blue light emission indicates a semi-acidic body of water. The lights are housed on the top of the pHloat and are illuminated under a paper origami shade. As to not further contribute to environmental pollution, a rope (not pictured in the 3d models) should be attached to each pHloat so it can easily be retrieved from the water (this allows for the pHloats to also be affixed to a particular area measuring passing water).pHloat is designed to create a social awareness of pollution in local rivers, streams, and lakes. It also functions as visual expression of concern for the emission of dangerous chemicals into our atmosphere. pHloats are designed to be released together to ultimately create floating mobile sculptures. Thus initiating a social space that engages locals living in the midst of these manufacturing industries to begin a dialogue about their environmental conditions.
