Greenhouse Climate Monitor Kit with ESP32 + Relay
Greenhouse Climate Monitor Kit with ESP32 & Relay – Bring Precision Automation to Any Room
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine a room that senses whether you are working, relaxing, or sleeping, then adjusts the lighting scene and fan speed to match your activity automatically. This kit equips you to build exactly that—a vision-based climate controller using the ESP32-CAM, a DHT22 environmental sensor, and a 4-channel relay module. Whether you're enhancing a home office, a studio, or a controlled environment like a greenhouse, you'll learn to fuse camera inference with real-world actuation.
What You'll Build
You'll assemble and program a system that captures images from the ESP32-CAM, classifies human activity into three distinct states using a lightweight model, and triggers relay outputs to switch lighting scenarios and fan operation. The OLED displays real-time temperature, humidity, and the detected activity mode. All components mount inside a sturdy enclosure box you wire and solder yourself. It’s the perfect foundation for an ambient intelligence system that reacts to human presence without any wearable device.
What You'll Learn
- Deploying a TensorFlow Lite Micro model on ESP32-CAM for on-device image classification
- Interfacing DHT22 sensor with ESP32 and displaying readings on a 0.96-inch OLED
- Controlling high-voltage appliances safely through a 4-channel relay module with flyback diodes
- Stable power distribution using an LM2596 buck converter and filtering capacitors

Who This Kit Is For
Engineers and serious hobbyists who want to merge computer vision with practical automation. Ideal for B.Tech ECE/EEE final-year projects, Smart India Hackathon prototypes, or makers building advanced home labs. If you've tinkered with Arduino before and are ready to tackle on-device ML inference, this kit will stretch your skills.
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 chat with the AI companion that has seen this exact project. If you need a human, our WhatsApp support responds within hours.
Can I train the activity classifier on my own data?
Yes, the kit includes guidance to capture images under your room’s lighting and retrain the model. The AI companion will walk you through data collection and retraining.
Does this kit require a soldering iron?
It includes a soldering iron and solder wire. All permanent connections on the prototype board require soldering.
What appliances can the relay module control?
The 4-channel relay can switch up to 10A per channel at 250 VAC, so LED light strips, table fans, or small exhaust fans are within safe limits.
Greenhouse — ESP32-CAM classifies room activity (working, relaxing, sleeping) and adjusts lighting scene and fan via relays.
