This page collects information about using electronic sensors for detecting hydrogen sulfide.
For information on the DIY photo paper method, see:

Arduino-based sensor prototype
Our first prototype used a digital sensor for hydrogen sulfide connected to an #arduino. Advantages of this system is that data from the sensor could be logged over time and that tool is reusable and portable. However the Figaro TGS 825 sensor itself is relatively expensive--approximately $60 for an individual sensor and $40 in bulk.
