Magnetohydrodynamic Flow Demo Kit with Arduino Uno + LED
Magnetohydrodynamic Flow Demo Kit with Arduino Uno: Build a Saline-Based MHD Sensor
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This advanced kit lets you build a working magnetohydrodynamic flow sensor, measuring the tiny pressure differences generated when a saline solution carrying current interacts with a magnetic field. You'll wire the ACS712 to detect Lorentz force and the MPX5010 pair to capture resulting pressure, logging results on an SD card with RTC-timestamped precision. Ideal for B.Tech capstone projects, physics lab demonstrations, or Smart India Hackathon prototypes.
What You'll Build
You'll assemble a complete MHD flow sensor system on a protoboard, solder all connections, and calibrate the ACS712 current sensor and MPX5010 pressure sensors. The final build displays real-time readings on an OLED, saves time-stamped data to a MicroSD card, and demonstrates the fundamental MHD principle—force induced by current moving through a magnetic field in a conductive fluid.
What You'll Learn
- Calibration of current and pressure sensors using Arduino
- Real-time data acquisition and SD card logging with an RTC module
- Interpreting Lorentz force from electrical current and magnetic field
- Soldering and prototyping a sensor circuit on PCB

| Compatibility checks | You verify every part compatibility with unknown MHD sensor requirements | Pre-tested as a complete MHD sensor system |
| Build support | Forums and scattered MHD research papers | AI companion trained on this exact MHD project |
| Time to first working build | Days of calibrating sensor offsets and noise | Hours, with step-by-step guidance for sensor calibration |
| Shipping coordination | Multiple sellers, varied delivery times | One shipment from Bengaluru in 3-5 days |
Who This Kit Is For
B.Tech students in electronics, instrumentation, and physics streams will find this kit directly applicable to sensor design, fluid dynamics, and data acquisition labs. It's ideal for final-year capstone projects, participants of Smart India Hackathon or ATL Tinkering Lab advanced challenges, and students at IIT, NIT, VIT, or BITS looking to demonstrate magnetohydrodynamic principles with actual hardware.
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?
Our AI companion provides diagnosis steps for wiring and calibration errors. If that doesn't resolve the issue, reach out on WhatsApp for direct support.
Do I need an external magnetic field? How strong?
Yes, a neodymium magnet is required (not included) to generate the Lorentz force on the saline current. A 0.5T magnet is sufficient. The kit measures the resulting ion movement.
Can I use this kit for a research project on MHD pumps?
Absolutely. This kit serves as a fundamental demonstration, and the pressure differential data can validate MHD pump models. The RTC-stamped SD card logs are ideal for lab reports.
What prior knowledge is needed?
You should be comfortable with Arduino programming, basic electronics, and soldering. This kit is not for absolute beginners; we recommend our intermediate kits first if you're new to sensor interfacing.
ACS712 measures Lorentz force on saline current. MPX5010 measures resulting pressure differential.
