Digital Automatic Livestock Weighing System Using Single Beam Load Cell.

The livestock market in Indonesia is still categorized as a traditional market due to the absence of the standard price and/or open sale. One recommendation that can be applied to livestock market is the application of weighing and management of livestock data, i.e. digital weighing system and cage structure with automatic door that can be opened and closed automatically. The proposed system is a cage that consists of digital scale based on single bending beam load cell with dimension 160cm x 80cm x 120cm. It has a sliding door driven automatically by DC motor. The livestock to be weighed is detected by the LDR-laser system which would notify the Mega 2560 arduino microcontroller to command the DC motor at the entrance and the exit spaces to open/close the door. The weighing results are displayed in LCD screen. The digital livestock scale could weigh linearly in the range of 0-440 kilograms with an average error of 0.265% and could measure a maximum weight of 620 kilograms. [ABSTRACT FROM AUTHOR]
