Instrument Tool of Baby Growth Portable Base on Arduino Uno R3

Growing up became the main parameter that parents should monitor and watch over on their babies, that includes height and weight to determine the health of the baby. Usually, midwives or medical personnel use a separate measuring instrument, this method makes the process to be long enough because the data collection is still manual. This study aims to make posyandu instrument for cadres or midwives in the aspects of growth measurement for baby. This measurement tool uses arduino uno R3 as data process from two sensors, including ultrasonic sensor to know the height of the baby, weight sensor using load cell with the results of data displayed via LCD (Liquid Crystal Display). The Result of this test obtained precision level that high with a percentage error level testing this device from 0 until 0,8 % on weight measurement and percentage error 1,1 until 2,1 % on height measuremen
