Aim
The aim of the project is to measure the height of a person using an ultrasonic sensor.
Problem statement
We all measure our height for various purposes. It is used in the field of health, sports and also defence. Manual measurements may not be precise. To improve the accuracy of height measurement we can use a height measuring cap. It is a cap which is worn like a normal cap which make use of Ultrasonic sound waves to measure the height. Through this, measuring of height is made easier and more accurate within seconds.
Material used
Brain: TinkerSpace Brain Board
Output: OLED display
Battery: Lithium-ion rechargeable battery
Component description
ULTRASONIC SENSOR
The function of Ultrasonic Sensor is to send ultrasonic sound waves to the floor back to the Brain unit (TinkerSpace board).
OLED DISPLAY
The function of the LCD/OLED Display is to display the measured value.
TinkerSpace Brain Board
TinkerSpace board acts as brain of this project, its function is to monitor the Ultrasonic sensor and control the LCD/OLED Display.
Battery
5V Lithium-Ion battery is used to power-up this project
Working description
When a person wears the cap, the ultrasonic sensor (input) measures the distance it sends the distance measurement to the TinkerSpace brain board(brain). The brain board displays the measurement (height) in an OLED
display (output).
Height Measured —> Measurement is shown in OLED display
Circuit Design (DesignSpace)
Step 1: Open TCode App -> Create New project -> Open DesignSpace
Step 2: Connect the Ultrasonic sensor to INPUT 3 of the Brain board.
Step 3: Connect the OLED display to the Bluetooth connector of the Brain Board.
Step 4: Connect supply and test project.
