Build a Research-Grade Data Logger for Plant Growth Studies

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

From tracking mango flowering in a university orchard to validating microclimate models for a Smart India Hackathon prototype, this kit puts professional phenology recording into your hands. It combines dual-point temperature and humidity measurement, precise ambient light sensing, and soil moisture monitoring - all timestamped by a real-time clock and stored as CSV on a microSD card. The result is a long-term dataset ready for correlation with plant growth stages, bud break, or crop yield, using the same principles deployed by agricultural research stations.

What You'll Build

You assemble a fully integrated field logger around an Arduino Mega 2560. Two DHT22 sensors capture air temperature and humidity at different heights above the canopy or within the crop layer. A BH1750 measures photosynthetically active light, while two soil moisture probes track root-zone water content. The DS3231 RTC stamps each reading to the second, shown live on a 0.96-inch OLED, and the MicroSD module writes CSV rows at intervals you set. Power it with a 9V battery and leave it running for weeks, then pull the SD card and analyze the data in Excel, Python, or R.

What You'll Learn

• Interfacing multiple I2C and analog sensors simultaneously on an Arduino Mega without address conflicts
• Building a reliable time-series logging system using an RTC and SD card, with error recovery for missing media
• Designing a robust data acquisition circuit on prototype PCB and managing sensor noise with decoupling capacitors
• Linking environmental variables to plant phenology by graphing temperature, humidity, light, and soil moisture trends

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This advanced kit fits B.Tech Agri, ECE, and Environmental Science students who need a field-deployable data recorder for capstone projects or Smart India Hackathon prototypes. Researchers at ICAR institutes, ATL Tinkering Lab mentors, and botany undergraduates will find the sensor combination ideal for phenology networks. It also suits CBSE Class 12 students with strong programming skills and a biology-computer elective, giving them a genuine research-grade tool to explore climate-plant interactions.
