Heiman Zigbee Gas Detector

Natural gas is 70 to 90% methane. Natural gas and methane are both slightly lighter than air. Propane is the common flammable gas that is heaver than air. This makes it generally more dangerous since the propane can get trapped in something like a basement or sump. Keep the detector low for propane.
