These Acetylene (C2H2) and Ethylene (C2H4) Sensors have Low Crosstalk and detection ranges of 10, 100 or 200ppm.  They also are available with high performance digital output.

The gas detection industry use ETO sensor to detect Acetylene and Ethylene (Ethene).  The problem using ETO sensors is that they don't have good selectivity.  They react to many other gases.  See the comparison below. 

 If selectivity is an issue, the SemeaTech Acetylene (C2H2) and Ethylene / Ethene (C2H4) sensors are way better.  No comparison in the technology.
