Greenhouse gases (GHG), mainly methane (CH4) and carbon dioxide (CO2), can be
generated in agricultural activities, not only in waste but also in the process of breathing of
livestock. The Theory of Inventive Problem Solving (TRIZ) is an innovative Russian
methodology that allows finding the solution to a problem raised. This paper presents the use of
two TRIZ tools to design a non-invasive prototype that detects CH4 and CO2 emitted by cattle in
real time. The tools were the matrix of technical contradictions and the nine-screen analysis with
which the parameter to be improved (A) was found and the best possible solution to design a
prototype that allows quantifying gases for animal welfare, Final Ideal Result (IFR) a wireless
module with a sensor system for each of the gases placed on the bovine head, which convert the
detected gas into an electrical signal to be sent wirelessly to a range of 1.5 km in free space at a
receiver for its visualization representing the parts per million (ppm) of CH4 and CO2 that the
bovine is generating during the measurement
