Abstract A integrity wheat component quickly measuring apparatus which based on NIR LED was developed, by using new chip and designing software. While providing a lower cost apparatus, it also provides quick answer speed and smaller size for fieldwork of wheat’s components measuring. The apparatus is made up of NIR LED, interference filter, lens, Si photronic detector, microprocessor system and calibration model. Compared with other instrument, the apparatus has many advantages, such as compact space, simple structure, low power waste, and anti-shake. This paper introduces the design of the apparatus, and predicts the concentration of wheat protein. The apparatus can realize non-damage measurement of wheat components’ concentration on fieldwork.
