摘要
介绍了单线数字温度传感器DS18B20的特点和工作原理,给出以DS18B20和单片机为核心的鸡舍实时温度自动控制系统的硬件及软件设计方案。该系统有越限报警功能,并能根据温度的高低控制风扇转动。实践证明,该装置测量精度高,控制性能良好,能满足鸡舍温度调节的实际要求。
The characteristic and principle of the single wire digital temperature sensor DS18B20 has been introduced in this paper, and it proposed the hardware and software design plan of Chicken coop real-time temperature automatic control system which take DS18B20 and the single chip microcomputer as the core. The system has the function such as alarming overreach limit and controlling fan rotating, experience proved that the system have high measuring accuracy and good controlling performance, it can meet the needs of chicken coop temperature adjusting.
