Corrosion Rate Electrochemical Monitor Kit with Arduino Uno
Arduino Corrosion Rate Monitor Kit – Galvanic Current Data Logger
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build a real-time corrosion rate monitor that quantifies galvanic current between dissimilar metals in different electrolytes. This advanced STEM kit uses the ACS712 current sensor to capture microamp-level corrosion currents, logs data to an SD card with timestamps, and displays results on a 16x2 LCD. Designed for B.Tech and research students investigating material degradation, the project delivers lab-grade accuracy in a hands-on format.
What You'll Build
A portable electrochemical station that precisely measures corrosion current between two electrodes submerged in an electrolyte. The Arduino Uno reads the ACS712 output, compensates for temperature via the DS18B20 probe, and records conductivity with the TDS EC meter. All data is stored on a microSD card with RTC timestamps and presented on an LCD in real time — giving you a complete corrosion rate profile for any metal-electrolyte pair.
What You'll Learn
- Quantify corrosion rate using galvanic current measurement instead of weight-loss methods
- Interface precision analog sensors (ACS712, DS18B20) with Arduino and calibrate offset
- Log multi-sensor data to microSD with DS3231 real-time clock for long-duration experiments
- Assemble and solder a complete data acquisition system on a prototyping board

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 to chat with your AI companion, or send a WhatsApp message to our build support team — we’ll guide you step by step, specific to your corrosion monitor assembly.
Can I use this kit to test corrosion in real-world water samples?
Yes, the setup measures galvanic current in any conductive solution, making it ideal for testing tap water, seawater, industrial coolants, or even soil extracts.
Does this kit include the electrodes and electrolyte solutions?
The kit provides all electronic components. You supply your own metal electrodes (copper, zinc, steel, etc.) and electrolyte (saltwater, NaOH) — electrode selection and preparation guides are included in the build manual.
How long can I log data continuously?
A 9V battery powers the logger for 3–4 hours; for extended monitoring, connect the Arduino to a USB power bank and the microSD card can store millions of readings across days.
ACS712 measures galvanic current between dissimilar metals in different electrolytes. Quantifies corrosion rate.
