Electrolysis Current Monitor Kit with Arduino Uno
Arduino Electrolysis Current Monitor Kit – Measure Gas Production Rate
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform a simple water electrolysis experiment into a data-driven science project. This kit lets you build a real‑time current monitor that displays the exact electrical current flowing through your electrolysis cell and estimates the rate of hydrogen and oxygen gas production — making abstract chemistry concepts tangible. Ideal for CBSE science practicals, ATL tinkering sessions, and STEM fairs across India.
What You'll Build
You’ll assemble a portable current-monitoring station with an Arduino Uno, an ACS712 Hall‑effect sensor, and a 16×2 LCD. Once connected to any small electrolysis cell, it reads the current in amperes and calculates the estimated gas production rate in mL/min, updating the display in real time.
What You'll Learn
- Connect a current sensor to an Arduino and read precise analog values.
- Program the Arduino to convert ACS712 output to amperes and compensate for noise.
- Drive a 16×2 LCD with an I2C backpack for clear, stable data display.
- Apply Faraday’s laws of electrolysis to translate current into hydrogen and oxygen gas volume.

Who This Kit Is For
Perfect for CBSE Class 11‑12 students bringing electrochemistry experiments to life, ATL innovation labs seeking sensor‑based STEM activities, and young makers (ages 10+) building their first real‑world measurement tool. B.Tech ECE/EEE freshers can also use it for mini‑projects at IIT, NIT, VIT, and BITS campuses.
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 build companion, accessible via the QR code on your kit box, provides step‑by‑step troubleshooting. You can also reach our team on WhatsApp for human support.
Can I use regular tap water for the electrolysis experiment?
We recommend distilled water with a pinch of baking soda or table salt. The kit includes a safety guide to set up a proper electrolysis cell without damaging the sensor.
Do I need to know coding beforehand?
No prior coding is required. The Arduino sketch is provided and explained block‑by‑block, so you’ll learn as you upload and modify it.
How accurate is the estimated gas production rate?
The estimate uses Faraday’s laws and assumes 100% current efficiency. For educational purposes it gives a reliable relative measure; you can calibrate it further by collecting gas volume for an exact correlation.
ACS712 measures current during water electrolysis. LCD shows amps and estimates gas production rate.
