Design baby mass and height monitoring system based on Arduino and Android application

摘要

Baby mass and height are important parameters of their growth and development. Monitoring of these parameters still use the conventional method by writing the results of the measurement into the baby growth chartbook. In this work, we designed and develop the mass and height monitoring system using load cell sensor, ultrasonic sensor HC-SR04, Hall sensor UGN3503 and microcontroller Arduino UNO R3. The monitoring system involves two main parts including hardware of mass and height measurement tool and Android application system for displaying baby growth chart. The operation of the sensor was investigated by utilizing the various mass and length. Experimental results showed the load cell sensor possesses high accuracy of 98% and the ultrasonic sensor has accuracy of 99.32%. The Android application was developed to save the data and to provide the growth and development chart.
