Arduino-Based Automatic Weighing Machine Design

Abstract The advancement of automation technology is currently in a critical stage. Automatic weights are now a necessity for commerce and agriculture in order to improve small, medium, and large-scale business owner’ production. Automatic electrical technology plays a significant part in the development of weighing machines from conventional systems to intelligent power systems, which in this case refers to the process of weighting. The use of an automatic weighing machine can improve efficiency and productivity because an automated weigher can operate automatically without the need for human assistance. Precise and valid weighing results can reveal improved product quality. It can help reduce weighing errors and improve production efficiency. The Arduino Mega 2560 microcontroller and load sensor play an important role in the entire operation process of the automation system in the design of this automatic weighing machine. The research phase includes the process of design, assembly, and testing of the device. The mass measurement system is based on the principle of the work of the load sensor with a maximum capacity of 20 kg. The experiment’s findings demonstrate that this instrument can accurately measure masses. The entire weighing process for 1 kg rice, from initial storage to entering packing, takes approximately 12 seconds. Utilizing an effective automatic weighing system will assist reduce energy usage. This automatic weigher’s power design is low power, electricity consumption for weighing 2000 kg of rice is 0.23345 kWh.
