"基于AT89S52单片机DS18D20传感器的多功能温度检测器设计"

The graduation thesis "Design of Temperature and Humidity Sensor Based on AT89S52 Single Chip Microcomputer DS18D20" from Ying En University focuses on the importance and commonality of temperature as a crucial thermal parameter in modern metallurgy, petroleum, chemical, and power production processes. In harsh environmental conditions or high temperatures, ensuring the normal and safe operation of the production process, improving product quality and quantity, reducing labor intensity, and saving energy require precise measurement, display, and control of furnace temperature to meet process standards. The key to temperature control technology lies in faster and more accurate control of the required temperature. The design uses Protel DXP as the schematic drawing tool for creating a temperature detector development board with a PCB board according to the design requirements. The system utilizes the popular AT89C52 single-chip microcontroller, paired with a humidity sensor, temperature sensor, and A/D conversion for system control. Additionally, common circuits for digital display and status indicator lights are included to enhance the completeness and flexibility of the design. The overall structure of the design is compact and portable. In conclusion, this multi-function temperature detector design integrates various components to achieve precise temperature control in industrial processes, demonstrating the practical application of microcontroller technology and sensor integration in industrial settings. The design highlights the importance of temperature monitoring and control for maintaining the efficiency, safety, and quality of production processes in various industries.
