Photosynthesis Light Logger Kit with Arduino Uno + Sensor
Log Ideal Plant Growing Conditions with the Arduino-Powered Photosynthesis Light Logger Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Plants need the right balance of light and water to thrive. With this kit, young scientists build a portable data logger that measures ambient light using a precision BH1750 sensor and soil moisture levels, recording both over time to understand the ideal conditions for photosynthesis. Perfect for school science fairs, CBSE biology projects, or any curious mind aged 5–15.
What You'll Build
You will assemble a complete environmental monitoring station that reads light intensity in lux and soil moisture percentage, displays real-time values on a bright OLED screen, and timestamps every reading with an accurate DS3231 real-time clock. The logged data helps you analyze how light and moisture vary throughout the day, directly linking to plant health and photosynthesis.
What You'll Learn
- How to interface an I2C light sensor (BH1750) with Arduino Uno
- Reading analog soil moisture and calibrating for your soil type
- Displaying real-time sensor data on a 0.96-inch OLED screen
- Logging data with timestamps using a DS3231 RTC module

Who This Kit Is For
Ideal for school students (Class 5 to 10) exploring biology and electronics, CBSE project submissions, ATL Tinkering Lab activities, and young hobbyists curious about how plants interact with light and water. Also suitable for B.Tech 1st-year students learning sensor interfacing and data logging fundamentals.
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 access your AI build companion, which walks you through every connection and code upload. If you still have questions, our team responds on WhatsApp within hours.
Can this kit be used for a CBSE Class 10 science project?
Absolutely. The project directly demonstrates how light intensity and soil moisture affect photosynthesis, aligning with biology curriculum. You’ll have clear real-world data to present.
How do I power the logger for outdoor measurements?
Simply connect a 9V battery to the included snap. The whole setup is portable and can log readings for hours without a computer.
Is any soldering or prior coding experience required?
No soldering is needed—all connections use a breadboard. The kit includes ready-to-upload code, so even first-time builders can complete the project successfully.
BH1750 and soil moisture together log ideal photosynthesis light and moisture conditions.
