A PDA-based intelligent building service system has been developed to control heating, ventilation and air-conditioning (HVAC) components. The system can be connected to Ethernet network and communicate with PDA or computers. BACnet protocol has been incorporated in the communication process between a system server and other connected smart devices. Each component of the system can work individually according to preset control loop or respond to commands made by users through PDA.
