Build a 6-Node Wireless Environmental Monitor with NRF24 and Arduino Nano

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

Imagine monitoring temperature and humidity in every room of your house or across a greenhouse, all from a single handheld display. This kit lets you build a true star-topology wireless sensor network: one Arduino Nano acts as the central hub with a TFT screen, while five remote nodes each send DHT22 sensor data over NRF24L01 transceivers. You'll wire, program, and deploy all six nodes, learning real-world IoT architecture that scales from a classroom project to an industrial monitoring prototype.

What You'll Build

You will assemble and code a 6-node NRF24 sensor network. Five battery-powered Arduino Nano nodes read temperature and humidity from DHT22 sensors and transmit wirelessly to a hub. The hub Arduino processes all incoming data and displays it on a 1.8-inch color TFT screen, updating in real time. Packed in a portable enclosure, this becomes a practical weather dashboard for your home, farm, or lab.

What You'll Learn

• Configuring NRF24L01 modules for reliable multi-node communication
• Designing a star network topology with one receiver and many transmitters
• Interfacing DHT22 sensors and parsing temperature/humidity output
• Driving a TFT ST7735 display with graphics and textual readouts
• Managing power for battery-operated sensor nodes in a real deployment
