Wireless monitored control system for buildings heating based on AVR single-chip computer

This paper introduces a wireless data acquisition system for buildings heating based on AVR single-chip computer wireless interconnect technology,whose terminal-monitoring PC communicates with AVR single-chip computer on each floor through wireless channel,so as to monitor the operational status of the entire network.The paper also introduces the methods of enhancing the network parameter measurement accuracy through uncertainty analysis and compensation in the principle of ultrasonic flow-meter.
