摘要
介绍了单总线技术的特点,以单片机AT89C52为核心,设计了基于湿度传感器HIH3610和单线数字温度传感器DS18B20的数字化温湿度监测系统,同时给出了该系统的硬件结构和相应的软件设计。应用结果表明,该系统具有测量精度高、抗干扰性强、可靠性高和性价比好等特点,在工程实际应用中具有重要意义。
Characteristics of 1-wire technique were introduced. A temperature and humidity monitoring system based on humidity sensor HIH3610 and 1-Wire digital sensor DS18B20 was designed, the hardware structure and the software design were also described. Compared with old data acquisition systems, it has some features such as high accuracy, better anti-disturbance performance, higher reliability and higher performance-price ratio. It is of great significance in practical application of engineering.
