Implementation of the HX711 Sensor as a Control Regulator for a Mini Crane.

Abstract

In today's industrial sector, the involvement of technology is crucial across various aspects and industries. One of the most commonly used technologies in this sector is the crane, a tool designed to simplify and reduce the physical effort required by human workers when moving goods or materials. This machine is essential for handling heavy items that cannot be lifted or reached by humans or forklifts. However, in certain industries, there have been issues with crane failures during the process of material handling. These failures often occur when the weight being lifted exceeds the crane's capacity, leading to motor overload and potential damage to the crane’s motor due to excessive load. This research focuses on addressing these issues using the HX711 sensor, a device that measures the weight of loads placed on the crane. The study developed a system with a maximum load capacity of 5 kg, using the HX711 sensor to monitor and control the crane based on the weight being lifted. The weight data is displayed on an LCD (Liquid Crystal Display), providing real-time information about the load being handled by the crane. The goal of this study is to minimize crane malfunctions caused by overloading and to ensure the safe operation of the crane by preventing motor damage due to excessive weight. The research shows that the integration of the HX711 sensor into the mini crane system successfully aids in controlling the load lifted by the crane, thereby reducing the likelihood of damage caused by overloading. The sensor enables accurate weight measurement and load monitoring, helping to maintain optimal functioning of the crane. However, during the testing phase, some errors were observed in the HX711 sensor, which interfered with the system's performance. These issues highlight the need for further calibration and improvements in the sensor’s accuracy to ensure more reliable results in future implementations. In conclusion, while the system shows promising results in preventing crane damage due to overloading, further refinement of the HX711 sensor is needed to enhance its accuracy and reliability in real-world applications. The integration of such technology is key to improving the safety and efficiency of material handling in industrial environments.
