研究目的
To design and implement a microcontroller-based energy saver and management system that reduces energy consumption in electrical appliances by coordinating their use and minimizing human intervention in residential buildings.
研究成果
The designed system effectively reduces energy consumption by automating the control of electrical appliances based on occupancy and ambient conditions. It demonstrates the potential for significant energy savings in residential buildings, with implications for broader applications in energy management.
研究不足
The system's effectiveness is dependent on the accurate detection of occupants and ambient conditions. Potential areas for optimization include improving sensor sensitivity and expanding the system's applicability to a wider range of appliances.
1：Experimental Design and Method Selection:
The project was built around a PIC microcontroller (PIC16F876A) that coordinates hardware components including a PIR sensor for occupancy detection, an LDR for light intensity detection, and a thermostat for temperature measurement. The microcontroller processes these inputs to control electrical appliances via a load driver circuit.
2：Sample Selection and Data Sources:
The system was tested in a residential building setting to evaluate its efficiency in reducing energy consumption.
3：List of Experimental Equipment and Materials:
Components include a PIC16F876A microcontroller, PIR sensor (SB00622A-2), LDR, DS1621 thermostat, LCD display, load driver circuit (MOC3021, BT136 triac), and a power supply unit.
4：Experimental Procedures and Operational Workflow:
The system detects occupants' presence and ambient conditions to automatically switch appliances on or off. The LCD displays the system status, including temperature and lighting conditions.
5：Data Analysis Methods:
The system's performance was evaluated based on its ability to reduce energy consumption effectively and efficiently.
