Hai Friends,
We can sense H2 gas by two methods...
1. Calorimetric Detection - Gas concentration Vs. Temperature Rise ( Produced by the heat reaction on a catalytic)
Note : Its should be independent of coverage area for better response


2. Conductivity Detection - Gas concentration Vs. Change in electical conductivity ( Reaction of gas on the solid surface)


LEL of H2 is 4% .. so we cutoff the system before its reach that limit.. so 0- 80% LEL enough for us..



Step :
First purchase H2 sensor and make circuit for our own..



Help :


What are the h2 gas sensor suit for our requirement?
Give an idea to create circuit..


Thank You
