Greenhouse Climate Monitor Kit: Build a Wireless Multi-Sensor Network with ESP32 and 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.

Monitor a greenhouse environment without running a single wire. This kit lets you build a five-node wireless temperature sensor network that sends data to an ESP32 hub, which then renders a real-time interpolated heatmap directly in your browser — no cloud account required.

What You'll Build

You'll assemble five Arduino Nano-powered sensor nodes, each reading temperature and humidity via a DHT22, and transmitting data wirelessly using NRF24L01 modules. The ESP32 acts as the central receiver and web server, generating a live heatmap overlay of your room or greenhouse, with color gradients indicating temperature zones. The result is a fully functional climate monitor you can scale and customize for indoor farms, school labs, or home automation.

What You'll Learn

• Designing a multi-node wireless sensor network with NRF24L01 modules
• Programming Arduino Nano microcontrollers for data acquisition from DHT22 sensors
• Implementing an ESP32 web server to serve dynamic, real-time HTML pages with JavaScript and Canvas
• Generating interpolated heatmaps from sparse sensor data using algorithmic color mapping

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Created for CBSE Class 11-12 students exploring IoT in physics or computer science, B.Tech ECE/EEE undergraduates prototyping for Smart India Hackathon, and ATL Tinkering Lab participants building environmental monitoring stations. This intermediate kit assumes basic Arduino familiarity and a drive to build real-world sensor networks.

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.
