About the project
Aim
To measure a person’s height using an ultrasonic sensor and display the result on an OLED screen.
Components Required
- Arduino UNO
- HC-SR04 Ultrasonic Sensor
- OLED Display (128×64 I2C)
- Jumper Wires
- USB Cable
Working Principle
The ultrasonic sensor is placed at a fixed height above the ground. It sends ultrasonic waves and measures the distance to the person’s head. The Arduino calculates the person’s height using:
Height = Total Height of Sensor from Floor − Measured Distance
The calculated height is then displayed on the OLED screen.
Applications
- Height measurement systems
- Smart health monitoring devices
- Contactless measuring systems
- Science and engineering projects
