Our team design the optical detection device for concentrations of nitrogen dioxide. The system is fabricated based on the nitrogen dioxide absorbs the wavelength of light from 400nm to 550nm. Detection range is related to light path. When the light path is longer, the resolution will higher and the measurement range will smaller. Therefore, the system uses a light source which nitrogen dioxide absorbs and designs the longer light path. The light signals can be received by the photodetector convert to concentrations of nitrogen dioxide which transfer to computer or mobile immediately.

Our team design the optical detection device for concentrations of nitrogen dioxide. Compared with other benchmark companies, our optical detection device is superior to electrochemical products. For example, optical detection device has wider measuring range, response time less 3s, and higher detection accuracy.
