Abstract: This paper presents a cost-effective and accurate weight measurement system utilizing a strain gauge, Wheatstone bridge configuration, and an Arduino microcontroller. The strain gauge, attached to a bending beam, detects the deformation caused by applied weight, which is then translated into a change in resistance. This resistance variation is converted into a voltage signal using a Wheatstone bridge circuit and amplified to a level suitable for the Arduino’s analog input. The Arduino microcontroller processes the analog signal, applies calibration factors, and displays the weight measurement on a connected display. The system’s performance is evaluated through experimental testing, demonstrating its reliability and suitability for various weight measurement applications requiring affordability and ease of implementation.
