【摘要】 在现代生活中,人们用车的频率愈来愈频繁,在冬季和夏季当汽车停止不动而车内还使用空调冷气或暖气时,发动机所排出的一氧化碳很容易泄漏到车厢内,危及人们的生命财产安全。本设计采用MQ-7气体传感器来检测气体,用单片机控制声光报警装置进行报警和LCD160A显示检测气体浓度。该设计提高了检测气体的灵敏度同时可随时显示室内CO浓度,以便人们观察。复位电路设置报警的初始值方便人们使用且提高了人们在的日常生活的安全性。更多还原

【Abstract】 Frequency in the modern life, people use it more and more frequent, in winter and summer when the car stop and the car also USES air conditioning air conditioning or heating, engine exhaust carbon monoxide is easy to leak into the car, endangering people’s life and property safety This design using the MQ-seven sensors to detect gas, using single-chip microcomputer control sound and light alarm device for alarm and LCD160 A display detecting gas concentration The design improves the detection of the sensitivity of the gas may at any time according to indoor CO concentration at the same time, so that people observe The reset circuit sets the initial value of the alarm, which is convenient for people to use and improves the security of People’s Daily life更多还原
