Based on greenhouse environment as the research object, this paper introduces the temperature and humidity temperature and humidity measuring circuit, microcontroller peripheral circuit, software flow, assembly language source program design, the design process of the data acquisition system and the realization of the simulation method. The method can improve system development efficiency, shorten the cycle and reduce costs, provides a means for the development of single-chip microcomputer system. Results show that the design of environmental parameters, temperature control precision is stable in o. 1 ,℃ humidity of the error can be controlled within + / - 2.0% RH.Key words: Protues, STC89C51, DHT11, LED1602, temperature and humidity目 录1 前言..........................................................42 整体方案设计.....
