Design of Automobile Exhaust Emission Detection and Alarm System
Year: 2025
Type: article
Abstract: The number of automobiles has increased dramatically, and vehicle exhaust has a serious impact on air quality, which has become a major factor of urban air pollution. The automobile exhaust emission detection and alarm system designed in this paper is firstly based on the circuit simulation test built in Proteus software, using STC89C52RC microcontroller as the core control element, and AD software to build the hardware circuit of the system, to realize the detection of exhaust, as well as adjusting the threshold, acoustic and visual alarm and display functions. Secondly, through the debugging and testing of the physical object, it realizes the more accurate detection of carbon monoxide, nitrogen oxides, methane and air quality. Finally, the detection value is displayed via LCD and an alarm is issued when the detection value exceeds the set threshold. The function of this detection and alarm system is in line with the initial design concept, and it has certain theoretical value and practical significance for automobile exhaust emission detection and environmental protection.
