HVAC Performance Monitor Kit with Arduino Nano + NRF24L01: Wireless 5-Zone Sensor Network with TFT Hub

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 five ordinary rooms into a live HVAC monitoring dashboard on a single TFT screen. This kit turns an Arduino Nano into a central hub that receives real-time temperature and humidity data from five independent battery-powered sensor nodes — each built around a DHT22 — using NRF24L01 wireless links. It’s a hands-on way to analyze HVAC system performance, pinpoint hot and cold spots, or teach core concepts of wireless communication and embedded data logging.

What You'll Build

You’ll assemble and program a complete star-network sensor system: five remote nodes that measure ambient conditions and transmit readings wirelessly to a base station. The hub processes incoming data and displays all five zone readings plus status indicators on the 1.8-inch TFT ST7735 display. The finished setup helps you evaluate HVAC distribution efficiency, detect insulation gaps, and understand how building automation systems collect environmental data — skills directly transferable to IoT prototyping and smart building projects.

What You'll Learn

• Program Arduino Nano microcontrollers for multi-node wireless data transmission using the NRF24L01 radio module
• Interface DHT22 temperature and humidity sensors and parse digital sensor data accurately
• Design a star network topology where a central hub receives and displays data from multiple sensor nodes on a TFT screen
• Troubleshoot wireless range, power supply noise, and timing issues in a real-world embedded system
