A smart sprayer comprises a detection system and a chemical spraying system. In this study, the development status and challenges of the detection systems of smart sprayers are discussed along with perspectives on these technologies. The detection system of a smart sprayer is used to collect information on target areas and make spraying decisions. The(More)
A multi-spectral camera is introduced to make up the traditional defects in this article, which is sensitive to NIR, red and green lights. It is with three CMOS sensors to collect the lights in the three wave-lengths. Besides, an FPGA is used to serve as the control unit. The information collected is stored as BMP files into a Compact Flash™ card.(More)
