The standard method of measuring height involves glancing at a scale that is at eye level—reading and estimating lead to inaccuracies. A more costly option is to use a commercial automatic height meter. These days, it's easy to construct a straightforward, precise, and affordable measuring instrument via the development of Arduino microcontroller boards and sensors. Clinically, the physical growth records are necessary for patient databased and will be measured every time during the checkup. Growth indicators like the height of the individual can be used in estimating the importance of calculating the body mass index (BMI), which helps diagnose conditions such as Marasmus and Kwashiorkor in children and pulmonary function. The digital height meter was measured using an ultrasonic sensor with an Arduino board. The ultrasonic sensor will measure the distance between the patient's heads and subtract it from 200 centimeters. The subject's height was shown digitally on an LCD panel. According to the results, the ultrasonic sensor's efficiency has an error range of 0.5-1.5% for measurements up to 200 cm. With a measuring error of 3%, the comparison between the typical measurement and the digital height meter resulted in a substantial discrepancy. This innovation in height measurement for hospital utilization is inexpensive and simple to build. It offers a quick method that is contactless, particularly to prevent infection while contacting the meter to measure height.
