Osmotic Pressure vs Concentration Kit with Arduino Uno + LED
Osmotic Pressure vs Concentration Kit with Arduino Uno + LED
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
You'll build a precise instrument that quantifies osmotic pressure by continuously weighing a dialysis bag as water moves across the membrane. Perfect for biology investigatory projects, this kit turns abstract chemistry into real-time data you can record and analyze.
What You'll Build
A self-contained osmotic pressure monitor that records mass changes every second onto a microSD card, displays live readings on an OLED screen, and timestamps each data point with a real-time clock. You'll have a complete experimental setup to investigate how sugar concentration affects water flux.
What You'll Learn
- How to interface a load cell and HX711 amplifier with Arduino
- Real-time data logging with an SD card and real-time clock
- Displaying sensor data on an OLED screen
- Applying physics and chemistry concepts in an engineering context

Who This Kit Is For
This kit is designed for CBSE Class 11-12 students working on biology or chemistry investigatory projects that require quantitative measurement. B.Tech first-year ECE/EEE students will find it a practical introduction to sensor integration and data logging. ATL Tinkering Lab mentors can use it to demonstrate real-world data-driven experiments.
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?
The AI companion provides real-time debugging help, and you can also reach out on WhatsApp for human assistance.
How do I calibrate the load cell for my osmosis setup?
The AI companion includes a calibration routine that walks you through zeroing and scaling using known weights.
Will this kit work for other diffusion experiments?
Yes, you can adapt the weight sensor to measure diffusion, evaporation, or any process involving small mass changes.
Do I need any chemicals or consumables not in the kit?
The kit provides all electronics; you'll need to supply dialysis tubing, sugar solutions, and beakers as per your experimental plan.
Load cell tracks mass change of dialysis membrane bag in solutions of different sugar concentrations.
