Build a 5-Node Wireless Sensor Network with Arduino Nano & NRF24L01

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

Picture a star-topology network where five remote Arduino Nano nodes independently measure temperature and humidity using DHT22 sensors, then beam their readings via NRF24L01 transceivers to a central hub. The hub’s Nano processes the incoming data and renders it live on a vibrant 1.8-inch TFT display. This kit is built for the college lab, Smart India Hackathon prototype, or IoT proof-of-concept that demands a hands‑on wireless sensing project that actually works.

What You'll Build

You’ll assemble and program five identical sensor nodes and one base station. Each node wakes periodically, captures environmental data, and transmits it using a collision-avoidance protocol. The base station receives all packets, decodes them, and updates the TFT screen with each node’s name, temperature, humidity, and signal quality. The result is a self‑contained wireless monitoring network that you can deploy to track micro‑climate variations across different rooms or a greenhouse.

What You'll Learn

• Configure NRF24L01 modules for reliable point-to-multipoint communication and tackle common interference pitfalls.
• Integrate DHT22 sensors over radio links—waking them, reading serial data, and packing it into transmit frames.
• Design and implement a star‑network protocol with time‑division access to prevent data collisions.
• Drive an ST7735 TFT display to render multi‑sensor dashboards, including bar graphs and node status indicators.
