Abstract:
Loadcell is an electromechanical device commonly called a Transducer, which is a force that works based on the principle of deformation of a material due to working mechanical stress, then converts the mechanical force into an electrical signal. The strain that occurs in the skin layer of the material is measured using a strain sensor or strain gauge. In this research, the electronic design of the load cell circuit will be carried out using the STM32 microcontroller programmed using the Arduino IDE. The components used in this design are load cell, HX711, RTC DS1307, STM32 microcontroller, SD Card Module, and 16x2 I2C LCD. The use of RTC DS1307 is to find out real-time time. Use of SD Card Module to store data so that it can be processed on a laptop/PC. As well as the use of a 16x2 I2C LCD to display time data and also the load calculated by the loadcell.
