Automated Greenhouse Seed to Harvest Logger Kit with ESP32 + DHT22
Full-Cycle Greenhouse Logger Kit — Track Seed to Harvest with ESP32, Camera & DHT22
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn your greenhouse into a data-rich research station. This kit captures time-stamped images and environmental readings at every critical growth phase — germination, vegetative expansion, and fruiting — so you can correlate light, humidity, soil moisture, and temperature with actual crop development. Whether you are a precision agriculture researcher, an agri-tech student, or a progressive farmer, this logging system gives you an unbroken visual and numerical record of the entire plant lifecycle.
What You'll Build
You will assemble and program an automated logger that uses an ESP32-CAM to take periodic photographs of your plants, while two DHT22 sensors, a BH1750 light sensor, and three capacitive soil moisture probes feed environmental data into a microSD card with RTC timestamps. The onboard OLED displays real-time status, and the whole system runs on a solar-charged 18650 battery pack inside a waterproof enclosure, ready for long-term deployment. By the end, you'll have a field-grade tool that produces a searchable log of images and CSV data files for post-harvest analysis.
What You'll Learn
- Programming the ESP32 to orchestrate multiple sensors and a camera module in a single, low-power loop
- Integrating the ESP32-CAM for scheduled image capture and storing JPEGs on a microSD card with the DS3231 real-time clock
- Designing a solar-powered 5V supply using a buck converter, TP4056 charge controller, and 18650 Li-ion cells for continual outdoor logging
- Timestamping and logging DHT22, BH1750, and soil moisture data into CSV format for later analysis in Excel or Python

Who This Kit Is For
This advanced kit is built for B.Tech and M.Tech students in agricultural engineering, ECE, or IoT who need a capstone project or want to compete in Smart India Hackathon with a live crop-monitoring prototype. It also suits researchers at IITs, NITs, and state agriculture universities running field trials, as well as data-minded farmers managing high-value greenhouse crops like capsicum or strawberries who want to optimize irrigation and light schedules based on actual growth-stage records.
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 inside the box to talk to the AI build companion that understands this specific circuit and code. If you need a human, our team is available on WhatsApp for personalised troubleshooting.
Can I adapt this logger for a different crop?
Absolutely. The sensor placements and camera angle can be repositioned inside the waterproof enclosure. You can also adjust the logging intervals in the code to match the crop's growth speed — sampling every 10 minutes for fast-growing microgreens or every hour for fruiting vegetables.
How long can the system run on battery and solar?
With the 6V 2W panel and two 18650 cells, the logger can run indefinitely under typical Indian sunlight if you keep the ESP32 in deep sleep between readings. The OLED and camera are only powered during active logging, conserving energy.
Does the kit come with preloaded code?
We provide fully commented source code and wiring diagrams in the AI companion. You'll flash the ESP32 Dev Board and the ESP32-CAM yourself, but the structure handles camera captures, sensor reads, RTC sync, and SD write routines out of the box so you can focus on customising logging intervals and thresholds.
Full-cycle logger tracking germination, vegetative and fruiting stages. Camera + sensors at each stage.
