Abstract:
This research concerns the controller of HVAC for Building by using
Microcontroller, which uses the difference between the set value and the present
value building temperature. The difference is assumed to affect the compressors,
Heaters, Fans in order to achieve the desired set point. The project involves
protection alarm system for HVAC system, designing a controller and performing
a simulation to analyses the performance of the designed controller using Bascom-
AVR Language and Proteus/Simulink. The controller is based on LM35
Temperature Sensor to control the temperature building. The result shows that the
controller is able to get a suitable temperature according to set point temperature
and the Controller give protection for HVAC system.
