摘要
本文对基于AT89C51的温度测量显示及控制系统进行了介绍,探讨了以传感器AD590,模数转换芯片ADC0809,单片机AT89C51为核心的温度显示及控制电路的实现方法。利用该系统可实现对环境温度的测量并通过四位七段数码管显示。并可通过键盘设置高低两个温度值,当环境温度超过这两个温度值范围时,系统可发出报警,并可控制相应电机的动作。
This temperature measurement based on AT89C51 display and control systems were introduced, discussed the sensor AD590, analog- digital conversion chip ADC0809, AT89C51 rnicrocontreller as the core temperature display and ＂control circuit implementation. Using this system can measure the temperature of the environment and, through four seven-segment digital display. And through setting high and low temperature value of the keyboard, when the ambient temperature exceeds the temperature range of these two, the system may issue a warning, and can control the corresponding motor action.
