Development of Smart Height Measuring Scale

The system proposed here is a smart height measuring system. A smart height measuring system has been developed in this project. There are several methods used to measure human height. In this research, we develop a human height measurement scheme. In our scheme, we calculate the height with an Ultrasonic sensor. Two round-looking parts in the ultrasonic sensor are called the ultrasonic speakers. When a 40 kHz sound wave collides with a solid surface, it bounces back (echoes). The echo is detected by the other. We may estimate the distances between the sensor and the item by measuring the overall time it takes to complete this operation. It measures the height of a human more accurately (2 cm to 13 feet). We have an extra feature comparing to the existing market products and that is Mobile Application. We can easily take the measurements using the app.
