The Design of Low-Cost Stand-Alone Microcontroller-Based Wireless Ultrasonic System for Process Monitoring and...

Area of Science:

• Applied Physics
• Embedded Systems Engineering

Background:

• Ultrasonic technology offers noninvasive, nondestructive analysis with low component costs.
• Existing ultrasonic setups require bulky, expensive auxiliary devices like signal generators and oscilloscopes.
• These additional components reduce portability, stability, and increase system complexity.

Purpose of the Study:

• To develop a real-time, portable ultrasonic system for analysis and process monitoring.
• To eliminate the need for external devices, reducing cost and improving portability.
• To create a stand-alone ultrasonic measurement solution.

Main Methods:

• A microcontroller-based system was designed for portability and small size.
• Integrated Bluetooth Low Energy (BLE) for remote control capabilities.
• Incorporated a battery for stand-alone, untethered operation.

Main Results:

• The developed system demonstrated high correlation with a commercial module in mixture analysis.
• The system's portability and battery power allow for use in confined spaces like incubators.
• Remote control via BLE enhances operational flexibility.

Conclusions:

• An embedded ultrasonic measurement system and software were successfully developed.
• The system functions as a stand-alone device for analysis, density measurements, and real-time process monitoring.
• This innovation addresses the limitations of traditional ultrasonic analysis setups.
