Sunlight Hours Meter Kit with Arduino Uno + Sensor
Sunlight Hours Meter Kit: Optimize Plant Sunlight with Arduino Uno & OLED Display
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 thrive or wither depending on sunlight—but guessing the right spot wastes time and seedlings. This kit lets you build a dedicated sunlight hours meter that records cumulative lux-hours throughout the day, giving you hard data to choose the perfect window sill, balcony corner, or garden patch. The BH1750 sensor captures precise light intensity, the RTC timestamps every reading, and the OLED display shows real-time totals so you can experiment with placement and confirm which location delivers the exact light your plants need.
What You'll Build
You’ll assemble a compact, battery-powered sunlight logger that measures ambient light every second and integrates it into lux-hours—a unit that tells you how much usable light a spot receives daily. After a full day of logging, the OLED screen presents the accumulated value, allowing direct comparison between different test locations. Place it among your seedlings, move it across a balcony, and determine whether that “bright indirect light” spot really meets your ficus’s requirements.
What You'll Learn
- Interface I2C sensors (BH1750 and OLED) with Arduino Uno R3
- Integrate a DS3231 real-time clock to timestamp light measurements
- Calculate cumulative lux-hours from continuous sensor streams
- Apply data logging concepts to a practical agriculture or home gardening problem

Who This Kit Is For
Young makers (10+) who want a hands-on electronics project with a direct connection to plant care will find the soldering-free breadboard assembly rewarding. CBSE and ICSE students building science fair experiments on phototropism or agricultural efficiency can use the logged data for analysis. ATL Tinkering Lab facilitators looking for agriculture-focused STEM kits will appreciate the real-time application, and home gardeners curious about quantifying sunlight on their balcony can finally move guesswork into informed plant placement.
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 box’s QR code to launch the AI companion, which knows every connection and code line for this sunlight meter. You can also send a WhatsApp message to our support team for a quick reply.
Can I use this kit without any prior Arduino experience?
Yes, the kit is designed for beginners. The AI guide walks through breadboard setup, wiring, and code upload, so even a first‑time maker can complete the meter in a few hours.
What types of plants can this meter help me place?
Any plant—from low-light peace lilies to sun-loving tomatoes. Measure a spot’s cumulative lux‑hours and match it to your plant’s daily light requirement to prevent stretching, leaf burn, or poor flowering.
Does this kit require soldering?
No soldering at all. All components plug directly into the breadboard, and the battery snap powers the Arduino via its DC jack, making assembly clean and reusable.
BH1750 lux sensor tracks daily sunlight accumulation and shows lux-hours on OLED. Helps optimise plant placement.
