Design of embedded temperature supervisory terminals based on GPRS and DS18B20

摘要

it focuses on ARM9 kernel S3C2410 microprocessor chips as the core. The temperature sensor choose single bus digital temperature sensor DS18B20. The author program DS18B20's drive in embedded Linux operating system. The paper design and implement to access the mobile data in the terminals and can easily access the Internet through GPRS networks. This system will be collected by remote wireless transmission of real-time temperature. The system structure is of clarity, generality and extensibility.
