Antibiotic Effectiveness Monitor Kit with Arduino Uno + Sensor
Monitor Antibiotic Effectiveness with Arduino Uno: Build a Real-Time Turbidity 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.
Antibiotic resistance is one of today’s most pressing scientific challenges. With this kit you construct a precise instrument that uses a turbidity sensor to track how bacterial broth clears—or doesn’t—when an antibiotic is introduced, giving you a hands-on window into microbiology and pharmacology. You’ll be able to compare a treated sample against a control and see the antibiotic’s effect in real numbers, just like in a professional lab.
What You'll Build
A self-contained data logger that measures, time-stamps, and displays turbidity data from two experimental setups—one with antibiotic, one control. The 0.96in OLED shows live turbidity readings as the DS18B20 monitors temperature for consistent conditions. An SD card stores a CSV file you can graph later to produce classic bacterial growth curves, while the DS3231 RTC ensures every data point carries an accurate timestamp.
What You'll Learn
- Calibrating a turbidity sensor to measure bacterial density (optical density equivalent)
- Integrating a DS3231 RTC for precise time-stamped data logging
- Logging sensor readings to a MicroSD card in CSV format and graphing them in a spreadsheet
- Interpreting growth curves and the concept of minimum inhibitory concentration

Who This Kit Is For
Designed for CBSE Class 11-12 students bridging biology and electronics, B.Tech Biotechnology or ECE undergraduates, and participants in the Smart India Hackathon or ATL Tinkering Lab projects. If you’re tackling an investigatory project on antibiotic action, bacterial resistance, or biosensors, this kit provides the full measurement setup in one package without the hassle of sourcing and verifying individual components.
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, accessed via QR code, knows this exact circuit and wiring. You can also message us on WhatsApp for hands-on troubleshooting assistance from our support team.
Does this kit include bacterial cultures or antibiotics?
No, to maintain safety and sterility, you’ll need to supply your own bacterial cultures and antibiotic discs. We provide a detailed guide on preparing samples safely and suggest easily available strains suitable for school labs.
Can I test multiple antibiotics at once?
Yes, the breadboard and extra resistors allow you to add up to two additional turbidity sensors for parallel experiments. Our AI companion can help modify the wiring and code to log data from all sensors simultaneously.
How do I power the monitor during long experiments?
The 9V battery snap powers the Arduino for portable use, but you can also connect a USB power bank or laptop for longer logging sessions. The DS18B20 temperature probe helps you account for temperature effects on bacterial growth.
Turbidity sensor measures bacterial broth clarity over time with and without antibiotic.
