Ultrasonics Cavitation Monitor Kit with Arduino Mega
Build an Ultrasonic Cavitation Monitor with Arduino Mega — Precision Instrumentation Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Harness the power of ultrasound with a custom-built cavitation monitor that precisely tracks the moment bubbles collapse. Whether you’re optimizing cleaning baths, sonochemistry experiments, or ultrasonic welding setups, this advanced kit equips you with a lab-grade measurement tool you construct and understand from the ground up. The high-frequency piezo transducer drives an ultrasonic field while a 16-bit ADS1115 ADC continuously measures impedance — the tell-tale signature of cavitation onset.
What You'll Build
A standalone instrument that drives a 40kHz ultrasonic transducer while simultaneously measuring impedance through a high-resolution ADS1115 ADC. It detects cavitation onset by tracking minute impedance shifts, logs every event with microsecond timestamps to MicroSD, and displays real-time waveforms on a 1.8-inch TFT screen. The system is powered by an Arduino Mega, making customization and further experimentation straightforward.
What You'll Learn
- Signal generation and analog conditioning using the AD9833 DDS and dual LM358 op-amps
- High-precision impedance measurement with the ADS1115 16-bit ADC
- Real-time data logging, RTC timestamping with DS3231, and storage on MicroSD
- Embedded system integration: TFT display, user input, and sensor fusion on Arduino Mega

Who This Kit Is For
This kit suits B.Tech final-year students in Electronics, Instrumentation, or Mechatronics engineering tackling ultrasonic process control projects. It’s equally at home in research labs at IITs, NITs, VIT, or BITS Pilani prototyping cavitation monitoring for sonochemistry or industrial cleaning, and for Smart India Hackathon teams needing a reliable sensor system. If you're comfortable with a soldering iron and ready to dive into analog front-ends, this build will stretch your capabilities.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to access your AI build companion, or message us on WhatsApp — our team and the AI both know this circuit intimately.
Can I use this kit to monitor cavitation in a real ultrasonic cleaner?
Yes, the included 40kHz transducer is designed for immersion; the monitor tracks impedance changes that correlate with cavitation intensity, making it suitable for benchtop ultrasonic baths.
Do I need an oscilloscope to calibrate the system?
No, the kit’s ADS1115 16-bit ADC and onboard signal processing allow calibration via the TFT screen using the provided firmware.
Is soldering experience required?
Yes, this is an advanced kit — you'll assemble the analog front-end and power supply on prototype boards, so basic soldering skills are necessary.
High-frequency piezo transducer drives ultrasonic bath. ADS1115 monitors cavitation onset by impedance shift.
