DESIGN AND CONSTRUCTION OF A DIGITAL SCALING SYSTEM FOR WEIGHT MEASUREMENTS
Abstract
Because of the importance of measurement in human endeavours, the analog system of
measurement seems to be in adequate to meet human desire hence this work presents the
development of an electronic weighing indicator for digital measurement. The objectives
of the system were to read weight measured in the conventional analog form to digital form,
achieve high precision in measurement and calibration. The components used to achieve this
purpose are Load Cell, Hx711 Load Cell amplifier, Arduino Microcontroller, A DC source
(battery, and an LCD module. In this research, a 200kg load cell is used. The load cell sends
output signals of the mechanical weights measured to the Hx711 module which amplifies and
sends the output to the Arduino microcontroller. The microcontroller calibrates the output
signal with the aid of the load cell amplifier module before sending the signal which is already
converted to digital form to the LCD module for display. The system developed has proved
that a digital electronic weighing system can be low cost, miniaturized, detached and can
take accurate readings devoid of errors. Later on in this work, we were able to construct a
digital weighting scale that is able to take accurate measurement of object and items.
