本文介绍的除湿机控制器是采用MCS-48系列单片机结合外围芯片而组成的最小控制系统。它通过A/D0809选通一对PN结,分别感受干球温度和湿球温度,经过软件查表运算可显示环境温度、湿度,并可通过按键对待控环境湿度进行预置,当湿度超出预置范围时,由继电器的通断控制除湿机开关。单片机采用Intel8035,并对其程序存贮器进行扩展。 This article describes the dehumidifier controller is the use of MCS-48 series microcontrollers with peripheral chips and the composition of the smallest control system. It is through A / D0809 gating a pair of PN junction, respectively, feel the dry bulb temperature and wet bulb temperature, the software can be displayed through the software table look at the ambient temperature and humidity, humidity and humidity can be preset keystroke control, when the humidity exceeds the pre- Set range, by the relay off control dehumidifier switch. Microcontroller with Intel8035, and its program memory expansion.
