Nondestructive Fruit Ripeness Detection System and its Spectral Analyses

Abstract:

This work focuses on the nondestructive fruit ripeness detection system at difference maturity stages. The study involved a two-step approach which is the absorption and reflection spectral analysis. In this system, light dependent resistor (LDR) is used as the light sensor and displayed on the LCD screen of its resistivity. Portable spectrometer is adopted for measuring the reflection and absorption before processed by simple electronic Arduino-based circuit. The results of the photonic ripeness detection system show that the ripe fruit has higher light reflection rate in comparison to the unripe fruit. If the average value of the resistance is in between 400-600 the fruit is classified as still in immature period. Where as the resistance of 610-800 indicates the fruit is matured. The growth of fruit determines the difference ripeness levels and its resistivity too.
