Design of Gas Alarm Based on Single Chip Microcomputer

Abstract:
Nowadays, the widespread use of gas brings many conveniences to the family, but at the same time there are also safety hazards. Therefore, a gas detection alarm based on single-chip microcomputer is designed here. This system uses gas sensors, liquid crystal displays and so on to detect household gas. If there is a gas leak, an audible and visual alarm will sound. At the same time, the sensor monitors the gas concentration in real time. If the gas is discharged through the exhaust vent, the Global System for Mobile communication(GSM) is sent to the user to notify the user of the danger. The gas valve and the exhaust fan are controlled by the single-chip microcomputer to complete the emergency treatment of the gas.
