Arduino Turbidity & Temp Logger for Biology Projects Kit
Precision Temperature & Turbidity Logger Kit for Biology Projects with Arduino Uno
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Recreate the precision of sous-vide temperature control to run a real microbiology experiment. This kit turns an Arduino Uno into a data logger that monitors bacterial broth clarity with a turbidity sensor while holding the sample at a steady temperature-mimicking lab incubators. Use it to compare growth curves with and without antibiotics, logging every reading with timestamps to a microSD card.
What You'll Build
A self-contained monitoring station on a breadboard. The DS18B20 waterproof probe sits in your test tube, the turbidity sensor measures broth cloudiness, and the DS3231 RTC stamps each data point. A 0.96-inch OLED shows live readings, while the microSD module saves a CSV file you can graph later. The whole system can run unattended for hours, giving you publication-ready plots of bacterial growth phases.
What You'll Learn
- Interface an analog turbidity sensor and calibrate it against known standards to measure Nephelometric Turbidity Units (NTU).
- Use the DS3231 RTC module to create timestamps accurate to the second for long-duration logging.
- Store time-series data on a microSD card and analyse growth curves, lag phases, and antibiotic inhibition zones.
- Implement a PID-based temperature stabilisation loop in Arduino to hold a sample within 0.5�C of a setpoint.

Who This Kit Is For
CBSE Class 11-12 students designing investigatory projects in biology, B.Tech ECE/Biomedical students building biosensor prototypes, and participants in Smart India Hackathon or ATL Tinkering Lab challenges. It is also a standout choice for IIT, NIT, VIT, or BITS Pilani undergraduates needing a reusable data-logging platform for environmental or medical tech 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?
Scan the QR code to chat with the AI companion trained on this kit's wiring and code, or send a photo via WhatsApp and our team will respond within hours.
Can I leave this running overnight for a 24-hour growth curve?
Yes. The 9V battery snap powers the setup independently, and the microSD module logs continuously. The temperature control loop keeps the broth stable without a computer.
Do I need to buy bacterial cultures and broth separately?
For safety and freshness, this kit does not include biological materials. Your school lab should provide sterile LB broth, test tubes, and the bacterial strain under study.
Is the turbidity sensor safe for food if I want to use it for actual sous-vide cooking?
The sensor is intended for educational use and is not food-grade. Please use dedicated food-safe probes if you plan to cook with it.
Cooking - Turbidity sensor measures bacterial broth clarity over time with and without antibiotic.
