摘　　要：介绍了基于AT89S52单片机的、适用于温室大棚温湿度测量的自动监测预警器的设计原理,包括硬件和软件的设计。装置采用AT89S52单片机作为控制器,使用单总线数字式温度传感器18B20采集干湿球温度,通过计算实时显示温湿度,并能够对超限温度进行设置和报警。该装置在西北农林科技大学园艺场日光温室中应用,结果表明:监测预警灵敏度与准确度符合设计要求,取得了良好的测量效果。This paper introduces design principles of the automatic temperature and humidity monitoring and warning device for greenhouses based on MCU AT89S52. MCU AT89S52 is used as the controller of this device ; and the single - bus digital temperature sensors （DS18B20） are used as collector of temperatures of wet and dry ball. The device is able to display real - time temperature and humidity by calculating and set and alarm abnormal levels of temperature. The device has been applied to monitor and warning the levels of temperature and humidity at the horticulture field of Northwest A＆F University, and the results satisfy the requirement of the design and application.
