Electronic Hydrogen Sulfide Sensors

This page collects information about using electronic sensors for detecting hydrogen sulfide. For information on the DIY photo paper method, see: https://publiclab.org/hydrogen-sulfide-photopaper **** ### 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](http://figarosensor.com/gaslist.html) itself is relatively expensive--approximately $60 for an individual sensor and $40 in bulk.
