ESP32 HVAC Performance Monitor Kit - Wireless Sensor Network Without a Router

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

This kit lets you build a three-node HVAC performance monitor that captures temperature and humidity from different zones in a room or building - all without connecting to your home WiFi. Each ESP32 acts as a sensor node, sending data directly to a central display over ESP-NOW, a low-latency peer-to-peer protocol built into every ESP32. You'll see real-time environmental readings and understand how air moves, where cooling fails, or where humidity builds up.

What You'll Build

You will assemble three independent sensor stations, each with its own DHT22 and power supply, and one master station with an OLED display. The sensor nodes transmit their readings wirelessly every few seconds, and the master aggregates the data, showing temperature and humidity for all three locations on a single screen. The system runs entirely without a router, making it perfect for portable HVAC audits or classroom demonstrations of industrial wireless protocols.

What You'll Learn

• Configure ESP-NOW for bidirectional communication between ESP32 devices
• Read and calibrate DHT22 sensor data for accurate environmental monitoring
• Design a multi-node sensor network architecture with power and signal filtering
• Program an OLED display to show real-time multi-zone data with minimal flicker

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

If you're a CBSE Class 11-12 student exploring IoT for your practicals, an engineering undergrad in ECE/EEE working on a mini project, or a Smart India Hackathon participant building a rapid prototype, this kit removes the connectivity headache. It's also perfect for ATL tinkering labs and B.Tech first-year workshops. IIT and NIT students can use it to understand ESP-NOW's real-world advantages over TCP/IP in peer-to-peer 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.
