Gas Alarm by IC

The article describes the home combustible gas detector. Main motivation for this construction was my 3 years old son who has very â€œpositiveâ€ relationship with the home hardware. Of course, nice buttons on the gas cooker are very interesting for him and he can hear nice hiss of the gas. The first situation like this accelerated my plan to develop some gas detector.
