Application of LED Light Source in NO2 Concentration Measurement
LED,as a new light source,has high light intensity, low power consumption,long life time,high reliability,and is easy to drive and connect to IC.Now it s taken into application on transportation,advertisement and instrument display.In this paper,the method for its spectrum acquirement has been introduced.And it analyzed its characteristics.The main Characters affect its performance are wave length,band width and dominant wavelength.In this paper,LED is applied on NO2 intensity measurement with spectral absorption method.The structure of the measurement system and its operating principle is introduced.And this system has the merits of low power consumption and small capacity.The measuring results are reliable.LED can be used in MO2 intensity measurement.And with this method,it s possible to make a portable/real-time measurement system.
