Project Overview

The Height, Base, and Angle Detection System is an advanced measurement tool designed to calculate the physical dimensions of large structures using trigonometry and electronic sensing. By utilizing an ultrasonic sensor to measure horizontal distance (the base) and an MPU-6050 Accelerometer/Gyroscope sensor to determine the angle of inclination, the system processes these variables through an Arduino microcontroller. This allows the device to instantly calculate the height of a target object—such as a building or tower—without needing physical access to the top of the structure. The results are displayed in real-time on an LCD screen, showcasing a practical integration of mathematics and embedded systems for civil engineering and surveying applications.

Future Work

Future improvements could involve adding a data logging feature using an SD card module to store multiple measurements for later analysis. Integrating a Bluetooth or Wi-Fi module would allow the device to transmit data directly to a smartphone app, where users could visualize 3D models of the measured structures. Additionally, implementing a Time-of-Flight (ToF) laser distance sensor would significantly increase the range and precision of the base measurement, making the system suitable for professional architectural surveying in various lighting and environmental conditions.
