Abstract：

This paper designs an indoor harmful gas detection system based on single chip microcomputer, which can monitor the harmful gases such as CO, CO2 and formaldehyde in the room, and timely issue an alarm to remind people to take necessary protective measures. The system uses multiple sensors for data acquisition, and processes and judges data through single chip microcomputer. It uses a buzzer and LCD display screen for alarm and display. The system has the advantages of simple structure, accurate data and real-time monitoring, which can effectively improve indoor air quality.
