Greenhouse Climate Monitor Kit v15
Greenhouse Climate Monitor Kit — ESP32 Mutual TLS MQTT for Professional IoT Security
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Move beyond basic sensor projects. Build a greenhouse climate monitor where the ESP32 authenticates itself to an MQTT broker using a client certificate stored in SPIFFS, and verifies the server’s identity. This isn’t just temperature and humidity logging — it’s a hard lesson in secure IoT device management that prepares you for real-world deployments.
What You'll Build
You’ll assemble a self-contained environmental monitor that publishes DHT22 and BMP280 sensor data to a Mosquitto broker over mutual TLS. The OLED displays real-time readings and connection status. Every message is encrypted, and the system refuses to connect if the broker’s certificate isn’t trusted. By the end, you’ll hold a fully documented project that demonstrates end-to-end security for greenhouse automation.
What You'll Learn
- Generate, format, and store client certificates in ESP32 SPIFFS for mutual TLS authentication
- Configure Mosquitto broker to enforce certificate-based client and server verification
- Interface DHT22 (temperature/humidity) and BMP280 (pressure/altitude) over I2C
- Implement a structured state machine that handles TLS handshake failures gracefully

Who This Kit Is For
Designed for final-year B.Tech ECE/EEE students, Smart India Hackathon participants, and IoT security enthusiasts who already know the basics of Arduino or ESP-IDF. If you’ve tinkered with MQTT but never implemented mutual TLS, this kit bridges the gap between hobby projects and enterprise-ready device security. It’s also an excellent foundation for a college major project or a prototype you can pitch at incubators.
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 access the AI companion; it’s been fed the entire wiring diagram, certificate generation steps, and common pitfalls. You can also message us on WhatsApp for human help.
Do I need a separate MQTT broker, or is one included?
The kit does not include a broker — you’ll set up Mosquitto on your own Raspberry Pi or cloud instance. The learning comes from configuring mutual TLS yourself, but the AI guide walks you through every command.
Can I use this for a college project submission?
Absolutely. The security focus and real sensor data make it a strong candidate for B.Tech final-year projects or Smart India Hackathon prototypes. The kit includes all hardware; you just document your implementation.
Are the certificates pre-loaded on the ESP32?
No. You’ll generate and flash them yourself — that’s the whole point. The guide shows you how to create CA, server, and client certificates with OpenSSL and store them securely in SPIFFS.
Greenhouse — ESP32 connects to Mosquitto with mutual TLS. Client certificate stored in SPIFFS. Verifies server certificate.
