Hydroponics Nutrient Monitor Pro Kit with ESP32 + DHT22
Hydroponics Nutrient Monitor Pro Kit: Your Full-Cycle Smart Farm Logger with ESP32 & 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.
Build a professional-grade nutrient and environment monitor that tracks your hydroponic grow from germination to harvest. Using a camera and precision sensors, you log temperature, humidity, light intensity, and substrate moisture at each growth stage — then analyse the data to maximise yield and quality in your smart farm setup.
What You'll Build
A self-contained, solar-powered logger that captures time-lapse images and sensor data onto a microSD card. The system delivers actionable insights for optimising nutrient solution strength, lighting cycles, and irrigation timing across all three plant growth phases. The waterproof enclosure and battery-backed clock mean your data stays intact even when mains power is unavailable.
What You'll Learn
- Calibrate DHT22 and BH1750 sensors for agricultural accuracy in humid greenhouse conditions
- Configure ESP32-CAM for time-lapse image capture and JPEG storage on microSD
- Implement DS3231 RTC for timestamped sensor readings and camera triggers
- Design a solar-powered 18650 battery system with TP4056 charging and buck converter regulation

Who This Kit Is For
This kit is designed for agri-tech professionals, researchers, and advanced hobbyists in India who are building automated hydroponic systems. It is ideal for Smart India Hackathon teams working on precision agriculture, B.Tech ECE/EEE students tackling IoT-based farming projects, and startup founders prototyping greenhouse monitoring solutions. If you are ready to move beyond basic Arduino sensors and integrate vision, solar power, and reliable data logging into a single deployable unit, this kit gives you the complete hardware foundation.
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?
Open the AI companion through the QR code or reach out via WhatsApp. It understands this exact kit and can troubleshoot wiring, sensor calibration, and coding steps specific to your hydroponic logger.
Can I monitor my hydroponic setup remotely?
The kit logs data locally to a microSD card for offline analysis. The AI companion includes guidance on extending the system with the ESP32's Wi-Fi to push data to free IoT platforms like ThingSpeak or Blynk for real-time remote access.
Does this kit include automatic nutrient dosing?
No, the Nutrient Monitor Pro Kit senses and logs environmental conditions. It does not include peristaltic pumps or nutrient delivery hardware. The companion provides schematics and code snippets to interface such components if you wish to expand the system later.
Is the waterproof enclosure suitable for outdoor use?
Yes, the IP65-rated enclosure protects the electronics in greenhouse or outdoor hydroponic setups. Combined with the solar panel and 18650 battery management, it can run completely off-grid.
Hydroponics — Full-cycle logger tracking germination, vegetative and fruiting stages. Camera + sensors at each stage.
