Timbangan Bayi Berbasis Sensor Load Cell
Baby Scales is a tool used to measure a baby's weight from newborn and how its development. By knowing the baby's weight, it can be indicated how the baby's health is in accordance with the normal or incompatible baby development table. Baby scales is commonly used in Posyandu or hospitals still use analog scales, so the measurement results obtained are less accurate. Load cell sensor based baby scales designed by this author uses a digital scale, which is equipped with an IC module HX711 that function as an amplifier or amplifier reading the results of a weight sensor/ Load Cell which then LCD shows the measurements result. While the microcontroller is Arduino so it is expected to produce more accurate measurements both in terms of readings and measurements. Data collection on this tool is done by measuring the weight of 2 different baby objects as a sample that has previously been done beforehand measurements on analog scales with a scale pointer as a comparison. Infant weight testing was carried out on samples of 2 different infants aged 6 months and 12 months. In addition this tool will also find out how the baby's condition in accordance with the limits of normal or not the baby's development is used as a reference comparison. Based on the measurements that have been made, the accuracy of the 6-month-old infant is 99.1% and that of the 12-month-old baby is 97,8%.
