MQ-2 and DS18b20

This is part of a arduino safety switch that I am putting together that will cut power to the printer if smoke is detected or the temp gets too high. The switch is arduino based using an MQ2 sensor for air quality and a ds18b20 for temperature. This is based on the Scalar MQ2 mount v2 - lowers the extension for the ds18b20 so the top from the Scalar MQ2 mount still fits
