Abstract
The detection system of air quality for the decorative environment based on DSP was studied in this paper. In the system, the gas concentration values about formaldehyde, benzene and ammonia are detected by the gas sensors of high precision, high selectivity and its signal adjusting circuit, the digital signal processor TMS320LF2407 DSP is used as the core controller, three sets of three bit digital tubes are adopted to display gas concentration value, sound and light alarm signals are send out with the light emitting diode and a buzzer, the ventilation device is configured to promote indoor air circulation and reduce pollution gas concentration. In addition, the modular program is written with the assembly language. The system has the advantages of simple operation and stronger practicability, but needs to further expand gas detection range.
