Precise H2 and CH4 sensor

Hi, thanks robtillaart

  1. I have 2 http://www.cooking-hacks.com/index.php/shop/sensors/mq8-h2.html?___store=es&___from_store=en sensors from that series, MQ-7, MQ-2, etc. Those cheap sensors can detect ch4 and h2, but as a global value combined with other flamable gases so maybe if you get a bunch of those sensors with different sensibilities to h2 and ch4 you can make an estimation about level of h2 and ch4...

  2. My goal is to detect the concentration of H2 and CH4 inside a bottle (with bacterias "eating" waste)

  3. Price: From 10 to 100 usd per sensor

Any advice?
