A-1 Wireless Gas Detector With Alarm

LNG (Liquefied Natural Gas) and LPG (Liquefied Petroleum Gas) are commonly used in daily life for many families. Both are colorless and flammable. An explosion would be caused by a spark or a flame if they severely leak. To detect the leakage of natural gas, the detector should be placed at higher position near the ceiling, because natural gas is lighter than air. And for LPG, a proper location for detection is about 30cm above the floor, since it's heavier than air.
