Weight Measuring Instrument for Testing the Nutritional Status of Toddlers Using the Anthropometry Method
Abstract
Stunting refers to impaired growth and development in children, typically resulting from chronic undernutrition, inadequate healthcare, and poor living conditions. It is characterized by a child being significantly shorter than the average height for their age. Stunting can lead to physical and cognitive deficits, affecting overall health and potential in adulthood. Early intervention with proper nutrition, healthcare, and sanitation is crucial to prevent and reverse stunting’s negative effects on a child’s growth and future well-being1. The research objective is to design a measurement tool for assessing weight and height in toddlers, equipped with an evaluation of their nutritional status. The purpose of determining nutritional status is to promptly address any deviations observed in a toddler’s growth, preventing further deterioration. The contribution of this study lies in measuring the weight and height of toddlers, which provides valuable information about their nutritional status. To assess nutritional status, the research primarily employs Anthropometry, a method that directly measures physical dimensions. The authors aim to create a module for measuring toddlers’ height using an Arduino microcontroller. The system incorporates a variable resistor (potentiometer) as a height sensor, which detects the toddler’s height and transmits this data via a Bluetooth HC-05 module to a PC for reading and display. Based on height measurements obtained from the module, the maximum error is approximately 0.35%, with an average error of 0.093%. This tool can be implemented for monitoring the growth of toddlers in terms of weight and height.
