sistem pengendalian temperatur ruangan menggunakan kontroller PID berbasis mikrokontroler (CD)
All this time, Air Conditioning temperature has been changed by pushing remote control as what temperature needed. If room temperature has been changed, Air Conditioning temperature that comes out has also to be changed till the temperature is suitable with room condition. Since the mechanism is complicated, it needs to make program controlling temperature that is come out from Air Conditioning automatically by noticing influence factor of temperature changing, such as: the material of the wall, season and room volume.
This research is made an appliance conduct automatically to control temperature at room by using minimum of system AT89C51. The Appliance use censor of temperature LM35, a peripheral of ADC 0808 to alter analogous language to digital, and also a display of LCD for the temperature appearance. In principle the appliances function to arrange temperature with controlling heater element and fan by using PID controller.
As a whole system from room temperature controller equipments use controller PID still not yet worked maximally, because its constraint lay in PID software that is to determine. Result obtained is driver relay show active respond and work as according with of the software.
