Photosynthesis Rate Oxygen Monitor Kit with Arduino Uno + LED
Photosynthesis Rate Oxygen Monitor Kit — Track Plant Oxygen Output in Real Time with Arduino
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
When aquatic plants like Hydrilla or Elodea photosynthesize, they release oxygen that dissolves into the surrounding water. This kit lets you quantify that activity under varying light conditions, turning a classic biology experiment into a precise, data-driven investigation. The dissolved oxygen sensor tracks O₂ levels while the BH1750 light sensor records ambient intensity, and everything is timestamped by the DS3231 RTC and saved to a microSD card for later analysis or lab report graphing.
What You'll Build
You’ll assemble a portable monitoring station that continuously measures dissolved oxygen and light intensity inside a water-filled beaker. The readings appear in real time on the 0.96-inch OLED display and are logged to a microSD card with accurate timestamps. By changing the distance or brightness of an external light source (or using natural sunlight through a window), you can correlate photosynthetic rate with light availability — essential for biology lab experiments, Smart India Hackathon projects, or B.Tech interdisciplinary work.
What You'll Learn
- Calibrating and interfacing a galvanic dissolved oxygen sensor with Arduino Uno for ppm-level measurements
- Using the BH1750 digital light intensity sensor to capture lux values in sync with oxygen data
- Implementing real-time clock (DS3231) timestamping for data logging on a microSD module
- Designing a compact, soldered prototype board layout for field-deployable sensing

Who This Kit Is For
Designed primarily for B.Tech ECE/EEE/Biotech students working on interdisciplinary lab projects or Smart India Hackathon prototypes that merge electronics with biology. CBSE Class 12 students exploring advanced biology-STEM integrations will also find the real-time data logging invaluable. Even ATL Tinkering Lab mentors and IIT/NIT undergrads can use it as a capstone mini-project to demonstrate sensor fusion and scientific instrumentation.
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 on the box to start a chat with the AI build companion; you can also send photos over WhatsApp for human-guided debugging if needed.
Can I use this kit with plants other than Hydrilla?
Absolutely. Any submerged aquatic plant that produces oxygen works — Elodea, Cabomba, or even algae samples from a pond.
Does the kit include the light source?
No, the kit measures light intensity via the BH1750. You supply your own desk lamp or use natural light; the sensor quantifies it, so you can test different brightness levels.
How do I export the logged data?
The microSD card stores timestamped DO and lux readings as a CSV file. Just plug the card into any computer and open it in Excel, Google Sheets, or Python for plotting.
Dissolved oxygen sensor tracks oxygen production by aquatic plants under different light intensities.
