It is a portable crop health analysis instrument based on dual-channel high-throughput spectral signals which derived from the incident and reflected light intensity of the crop canopy at red and near-infrared bands.

Meanwhile, it could calculate vegetation coverage, density and color content by images captured from the camera of smart phone.
