Build a Greenhouse Climate Monitor with ESP32, DHT22 & Zigbee MQTT Bridge

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Transform your greenhouse or school science corner with a live climate dashboard that reads temperature and humidity locally on an OLED display while publishing data to an MQTT broker over WiFi. The ESP32-C6 dev board takes on a dual role: it reads the DHT22 sensor directly, then acts as a Zigbee coordinator ready to onboard additional wireless sensors around your growing area. Whether you are prototyping a smart agriculture submission for the Smart India Hackathon or demonstrating IoT logging for a CBSE practical, this kit gives you a real, expandable system in a single afternoon of building.

What You'll Build

In four to five hours, you wire up a 400-point breadboard with the ESP32-C6, DHT22 temperature and humidity sensor, 0.96-inch OLED display, and supporting resistors and capacitors. Once programmed, the display shows real-time greenhouse climate readings. Simultaneously, the board establishes a Zigbee network and bridges any future Zigbee sensor data to MQTT, so your monitor seamlessly becomes part of a larger sensor mesh — a genuine IoT greenhouse manager you can extend with soil moisture, light, or CO2 modules.

What You'll Learn

• Reading a DHT22 sensor over a one-wire interface and converting raw data into usable climate metrics
• Driving an I2C OLED display to show live temperature and humidity values
• Configuring the ESP32-C6’s built-in Zigbee coordinator to form a network and bridge its messages to WiFi MQTT
• Structuring an Arduino IDE or PlatformIO project to manage MQTT topics, WiFi connection, and sensor/display control in a responsive loop

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This intermediate kit hits the sweet spot for CBSE Class 11–12 students working on IoT practicals, B.Tech ECE/EEE undergraduates prototyping for Smart India Hackathon, and ATL Tinkering Lab mentors who need a reliable greenhouse monitoring demo. Makers from IIT, NIT, VIT and BITS Pilani have used similar Compoden kits to jump‑start MQTT and Zigbee experiments without hunting down compatible breadboard components.

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.
