Greenhouse Climate Monitor Pro Kit with ESP32 + DHT22
Build a Greenhouse Climate Control System with ESP32 & AWS IoT Shadow
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Create a fully autonomous greenhouse monitor that reads temperature, humidity, and pressure, then controls fans, heaters, or misters via a 4-channel relay. The ESP32 syncs its entire state with an AWS IoT Device Shadow, so you can push desired settings from your AWS console or mobile app and watch the hardware react within 500 milliseconds. It’s the same pattern used in commercial AgTech deployments, now accessible in a single afternoon build.
What You'll Build
You’ll assemble a sensor module that captures climate data using the DHT22 and BMP280, hook up a DS3231 real-time clock for timestamped logging, and integrate everything on a prototype PCB. Once connected to AWS IoT Core, the device constantly shadows its actual readings and listens for desired-state changes—turning relays on or off on command. The finished unit sits inside the included enclosure, ready for your greenhouse or lab test bench.
What You'll Learn
- Reading calibrated temperature, humidity, and barometric pressure from DHT22 and BMP280 sensors over I2C/one-wire
- Implementing AWS IoT Device Shadow with JSON state documents to synchronize physical and cloud state
- Driving a 4-channel relay module from ESP32 GPIOs while reading back actual relay status for closed-loop control
- Power budgeting with the LM2596 buck converter and soldering a reliable field-ready prototype board

Who This Kit Is For
This kit is built for final-year B.Tech ECE/EEE students developing an IoT-based capstone project, Smart India Hackathon teams needing a reliable AWS-connected prototype, and postgraduate researchers at IITs, NITs, VIT, or BITS Pilani. It’s also the right starting point for professional developers prototyping greenhouse automation systems or anyone who wants to master real-time device shadows on the ESP32 platform.
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?
Your AI build companion (QR code on the box) walks you through every connection, code upload, and AWS configuration. If you need human help, reach our support team on WhatsApp directly.
How quickly does the relay respond to a shadow update?
The ESP32 checks for a shadow delta every 500ms, so your desired state change (e.g., turn on fan) is reflected in hardware within that window—often faster depending on network latency.
Can I monitor multiple greenhouses with this kit?
Yes, each kit is a standalone AWS IoT node. You can register multiple ESP32 devices under the same account and manage them from a single dashboard or Lambda function.
Do I need prior AWS experience?
The AI companion guides you through AWS IoT Core setup and device certificate provisioning. Basic familiarity with the AWS console is helpful, but step-by-step instructions handle the heavy lifting.
