Development of microcontroller based lemon ripening condition monitoring system

Abstract

This paper presents the development of microcontroller based lemon ripening condition monitoring system using National Instrument LabVIEW software. Ripening of the lemon occurs on its plant and is generally characterized from the changes in its color, size and the acidic level. In this paper, the ripening stages of the lemon are analyzed based upon change in their in colors at different stages. The ripening stages of lemon at the plant are analyzed directly from its image obtained from the wireless camera interfaced with the microcontroller board. The image data file is wirelessly transferred and stored using Wi-Fi communication in Dropbox. The image data file is retrieved from gmail server and is processed in LabVIEW to monitor the condition of lemon. On identifying the ripening condition of lemon, an email is send to the intended user account for picking the lemon and preventing it from over ripening.
