Abstract
This design is on shutting the wreath the control the system, and be constituted by 89 C51s machine of single slice, A/ D convert electric circuit, temperature examine electric circuit, degree of humidity examine electric circuit, control system. Temperature examination electric circuit will temperature that examine conversion electric voltage, should imitate the electric voltage after ADC0809 convert, enter 89 C51 the machine of single slice, machine of single slice pass to more input the temperature and set up the temperature to control the fan or electric stove to move the electric circuit, and be room inside temperature is within the scope of enactment, single slice the wrong fan or electric stove of machine send out the action. Realizes to examination big room plant grew temperature and soil with air degree of humidity, supervise and control, and can right over the scope of normal temperature, degree of humidity that condition proceed the solid hour handle, made the big room environment to get the good control.
Should design to still have to temperature of solid hour show function, to room inside environment the preparing of temperature establish the function?
