We usethe KD28 gas sensor probeand several componentstomake a combustible gas alarm device. When the combudstible gas of surrounding environment exceed a certain concentration, it can remind peopleto takemeasures. Debugging: adjusting W (1 minute later) can make circuit not alarm, and thenwe access gas lighters (butane) to gas-sensitive element alarm untilitreturns normal work after gas left. This device's features are less component, commissioning simple. Itcan be usedin the detection of flammable gas such as gas, liquefied petroleum gas, natural gas and smoke etc.
