In view of the safety production situation of coal mines in my country, a design scheme of gas monitoring and alarm system with ATmega16L single chip microcomputer as the core is proposed. The system uses LXK-3 sensor to detect the gas concentration in the mine, and uses ULN2803 driver to process it for real-time display. At the same time, nRF2401 is used to realize data transmission between upper and lower computers through wireless mode. When the gas concentration exceeds the limit, an audible and visual alarm is issued in time.
