摘要 在许多场合,及时准确获得目标的温度、湿度信息是十分重要的,近年来,温湿度控制领域发展迅速,并且随着数字技术的发展,温湿度的测控芯片也相应的登上历史的舞台,能够在工业、农业等各领域中广泛使用。
针对此领域的发展方向,本论文介绍了以AT89S52单片机为控制单元、温度传感器DS18B20与湿度传感器SHT10为主要控制器件,实现多点温度、湿度的测量、控制和显示。
本设计使用硬件描述语言Keil C51进行设计开发,采用μ VISION2的综合软件设计程序, 实现电路的设计的要求:温度测量范围为 -55℃ ~ +120℃,在 -10℃ ~ +85℃,精度为±0、5℃;湿度测量范围为:0 ~100%RH,精度为±4.5%RH;能实现温湿度上下限的设置及实现制冷/加热(去湿/加湿)的控制。
关键词: 温度测量 湿度测量 传感器 单片机 控制仪

abstract: in many situations, promptly accurately obtains the goalthe temperature, the humidity information is extremely important, thewarm humidity control domain development was in recent years rapid,and along with the digital technology development, the warm humidityobservation and control chip also corresponding mounted historical thestage, could in the industry, the agriculture and so on in variousdomains the widespread use.

  In view of this domain development direction, the present paperintroduced take the AT89S52 monolithic integrated circuit as thecontrol unit, temperature sensor DS18B20 and humidity sensor SHT10 isthe primary control component, realizes the multi- spots temperature,the humidity survey, the control and the demonstration.

  This design use hardware description language Keil C51 carries on thedesign development, uses mu the VISION2 comprehensive software designprocedure, realizes the electric circuit design request: Thetemperature survey
