多点测湿系统

The System of Multi-dot Humidity Measurement Based on Single Bus

介绍基于单总线器件DS2450的多点测湿技术,利用单片机AT89C51和湿度传感器组成传感器网络,实现多点测湿,由于该系统在测量现场直接将模拟信号转换为数字信号,能够远距离测量多点湿度,具有很高的测量精度;该系统可用于仓库测湿、温室控制和生产过程监控等领域。

In this article, a multi--dot humidity measuremeng system based on MCU is introduced, using DS2450, humidi- ty sensor and single chip build up sensor networks DS2450, which can detect the multi--dot humidity, gave the hardware circuit and the software. Because of the characterristic of 1--wire circuit, it can convert the analog signals to digital signals derectly and has the ability of measuring distance multi-dot humidity with high accuracy. This system applied in such domains as warehouse detecting humidity, greenhouse control system and supersisory productive process etc
