Our graduation thesis "Smoke Alarm Based on Single Chip Microcomputer" introduces a smoke alarm system designed to detect fire hazards in real-time. The system utilizes sensors, including temperature and smoke sensors, to convert signals such as temperature and smoke into detectable electrical signals. The amplified and filtered signals are then sent to an A/D conversion circuit to convert the analog signals from the smoke and temperature sensors into digital signals, allowing the single-chip microcontroller to determine if a fire has occurred on the scene. In the event of a fire, the system will activate a buzzer and indicator light to alert users to the presence of a fire. The high-performance single-chip microcontroller core and highly sensitive smoke sensor ensure the accuracy and reliability of the system. By utilizing both visual and auditory alarm forms, the system enhances the effectiveness of fire detection and notification. Keywords: Single-chip microcomputer, AT89C51, ADC0809, sensor. The design of this smoke alarm system aims to provide a reliable and accurate method for detecting fires and alerting individuals to potential dangers. By integrating advanced technology and sensor capabilities, the system is able to effectively monitor the environment and respond quickly to fire hazards. The use of a single-chip microcontroller as the core of the system allows for efficient processing and decision-making, ensuring prompt and reliable performance in emergency situations. Overall, the smoke alarm system based on a single-chip microcontroller represents a significant advancement in fire safety technology. By combining sensor data with intelligent processing capabilities, the system delivers a high level of accuracy and reliability in detecting fires and issuing timely alerts. This innovative design holds great promise for improving fire safety in various settings, from homes and offices to industrial facilities and public spaces.
