Abstract :
A real-time exhaust monitoring system that based on NDIR and ZIGBEE is proposed in accordance with the Lambert-beer law and the fact that gas could absorb infrared ray selectively. There are several characteristics of this system. First, a new non-dispersed infrared gas sensor with electro-modulated infrared photo-source is used, and the mechanical modulator that commonly appears in traditional method is saved. The application of a pyroelectric infrared sensor integrated with high-precision interference filter could be the second feature. The third feature is that a dual-wavelength single-beam technique is applied in the monitoring system. Meanwhile the characteristics and application of ZIGBEE in wireless detecting system is described. The real-time exhaust monitoring system is introduced in detail.
