Description

technical field [0001] The invention relates to an intelligent household gas monitoring system based on an amplification and filtering circuit, in particular to an intelligent household gas monitoring system based on an amplification and filtering circuit, which belongs to the technical field of household gas intelligent detection. Background technique [0002] The underground gas pipeline network in most cities in my country generally adopts the method of manual detection and management. The line-finding personnel carry portable detection equipment to detect the gas pipeline and its accessories. Once a leak occurs and reaches a certain concentration, an alarm signal will be issued, and then corresponding processing will be carried out. This method has certain flexibility and sensitivity, but this traditional detection method has many loopholes in time and space, and it is impossible to know whether the gas in the pipeline is leaking in a timely and effective manner. It requir...
