Design of Optical Raindrop Spectrometer Based on Embedded Microcontroller

Raindrop spectra distribution plays an important role in soil erosion, rainfall intensity, rainfall type, and so on. Traditional measurement of raindrop size distribution is based on filter paper, which can not achieve real-time, rapid and accurate observation. This paper proposes an optical raindrop spectrometer, which is designed based on embedded microcontroller. An embedded microcontroller is set as the control center of the system, combined with optical detection technology, high-speed signal acquisition technology, digital signal processing technology and embedded software design technology to realize online observation of raindrop size and falling speed, compute spectral distribution, draw distribution figures. According to raindrop size distribution, rainfall intensity and rainfall is calculated. Research production is also the basis for future research of precipitation type identification.
