Portable Gas Detector

With Summer and therefore the BBQ season approaching quickly, I wanted to build a simple handheld and portable device that can detect small gas leaks when connecting LPG gas bottles. When I originally started to investigate how to do this I expected it would be quite challenging, however, I came across the MQ range of sensors which allows you to easily detect a large number of gases.

The MQ range of sensors allows the user to detect all manner of gases from Alcohol to Ozone. Follow the chart
