Leave it too an engineer - Cornell students build fart detector
My guess is that a girlfriend complained and this was built to prove his farts weren't as bad as she claimed.

After learning in class how breathalyzers work, Robert Clain and Miguel Salas assembled a fart detector from a sensitive hydrogen sulfide monitor, a thermometer and a microphone and wrote the software that would rate the emission. A “slight perturbance in the air†near the detector sets it to work measuring the three pillars of fart quality: stench, temperature and sound. Temperature, Clain explains, is critical. The hotter a fart, the faster it spreads. “It beeps faster if it’s a high ranker, and a voice rates it on a scale of zero to nine,†he says. “If it ranks a nine, a fan comes on to blow it away. It even records the noise so you can play it back later.†After a few months of construction, they began field tests. “Well, the sample data wasn’t the entire school, but we definitely tested it,†Salas says.
