I don't know any cheap mass-produced sensors which have an odour
threshold of:

Odor Threshold: Ethanethiol=0.2 ppb, isopropyl mercaptan=0.024 ppb TBM=0.008 ppb

http://www.google.com/search?q=cache:www.oxychem.com/products/msds/m36047.pdf+mercaptan+ppb&hl=en

This is mindbogglingly low. Even while we're not canines, our rhinoequipment
is quite impressive.
