Abstract :
An instument for measuring height and weight while providing information
ideal weight for users will be very helpful. Therefore, in this study, it was
designed and realized a measuring instrument which can simultaneously measure
the height and weight as well as providing the ideal information whether or not
the weight measured. This instrument uses an Arduino Uno as the brain, the
ultrasonic sensor to measure the height and load cell sensor for measuring
weight. Data from the sensors is processed by the Arduino to get a body mass
index and ideal weight. The values of height, weight, and ideal weights will
display on LCD. After performing comparative tests, the results obtained for
erornya only 8.4%. This means that the success rate of the tool has been
successful.
