Design of an Indoor Air Quality Monitor System Based on ARM11
Abstract:
In this paper, a real time system based on ARM11 is designed to monitor the indoor air quality (IAQ) which includes the temperature, humidity and soot concentration. The system contains acquisition terminal and control terminal, and the two parts communicate through the wireless channel. The main function of the former is to collect IAQ indicators, while that of the later is to analyze and process the indicators collected, display the corresponding results. To effectively prompt or alarm the user, the core control unit of the control terminal creates corresponding control commands and texts to the speech synthesis chip which will drive the loudspeaker to sound. Hence, it plays an important role on the monitoring of the IAQ.
