Bin-ary is a self-contained gas detector that analyzes organic trash odor compounds and releases a subtle burst of scent when bad odor is detected. The prototype is meant to be used as a plugin to make trash bins and dumpsters smarter and prevent insalubrity in cities and villages. In order to detect the state of organic trash we primarily focused on the chemical compounds that are produced when food starts to rot or ripen: Hydrogen Sulfide (H2S), Ethylene (C2H4) and Carbon Dioxide (CO2).
