Optical device configuration of water content measurement on the green tea blend

Research output: Contribution to journalArticlepeer-review

Abstract

In this study the design of optical device configuratios was carried out to measure water content of green tea powder. The device configuration works by utilizing reflectance and absorbance phenomena, consisting of LED (λ = 970 nm), cuvette, LED driver, beam splitter and photodiode. From the measurement results of green tea powder obtained a linier consistent relationship between reflectance intensity in the range 0f 6%-58% water content variation, which decreases with increasing water content with gradient-8x10-3.
