Gas Sensor Sonification System

In this investigation, different gas sensors were used with Arduino and Pure Data (Pd), a visual programming language for computer sounds and other multimedia works, to output different noises through the Modular-Muse (mm) Library, an interface developed by Jiffer Harriman specifically for the creation and development of tones. Hydrogen Gas (H2), Alcohol Gas, Carbon Monoxide (CO), and Liquefied Petroleum Gas (LPG) sensors were all used to output these various sounds.

This system provided a different way of knowing the values of the different gas sensors. Each one has a different range that means different things. By creating a different sound for safe, moderate danger and dangerous, the system gives immediate auditory feedback with sound that doesn’t require looking at a display or interpreting a value.
This project was created as part of the CU Science Discovery Research Experience.
