ECE Lab Kit 9 Wireless Data Transmission
Build a Dual-Node Wireless Sensor Network with Arduino & 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.
Set up two Arduino nodes—one transmitting DHT22 temperature and humidity data, the other receiving and displaying it on an OLED—and run experiments to quantify wireless link performance: transmission range, packet loss percentage, and data throughput. This kit transforms a typical ECE lab session into a hands-on investigation of real-world RF behavior, perfect for coursework, mini-projects, and hackathon prototypes.
What You'll Build
A complete point-to-point wireless sensor link. The transmitter node reads environmental data and sends packets via nRF24L01; the receiver node displays live sensor readings and logs communication statistics. You can vary distance, introduce obstacles, and change data rates to see how each factor affects signal reliability. By the end, you'll have a fully instrumented wireless testbed with visual feedback on both ends.
What You'll Learn
- Configure nRF24L01 transceivers for reliable packet-based communication
- Measure packet loss percentage and calculate transmission success rate
- Analyze the impact of distance, obstacles, and data rate on wireless link quality
- Display real-time sensor data and link statistics on OLED screens using Arduino

Who This Kit Is For
This kit is designed for B.Tech ECE and EEE students performing wireless communication lab experiments, CBSE Class 12 students building sensor networks for ATL Tinkering Labs, and teams prototyping IoT solutions for the Smart India Hackathon. It also suits faculty at IITs, NITs, VIT, and BITS Pilani looking for pre-validated lab equipment that arrives ready to use.
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.
What if I get stuck during the build?
Scan the QR code on the box to access the AI companion, trained on every step of this kit. You can also message us on WhatsApp for real-time help from our team.
Can I modify the code to test different data rates?
Absolutely. The AI companion provides ready-to-use code snippets to switch nRF24L01 air data rates (250 kbps, 1 Mbps, 2 Mbps) and measure the effect on range and packet loss.
How do I measure transmission range accurately?
The kit includes a range-testing procedure with visual feedback on both OLEDs showing received signal strength and cumulative packet count. Walk the nodes apart and note when packet loss rises to define your link margin.
Is this suitable for a final-year engineering project?
Yes, it provides a solid foundation for wireless sensor network projects. You can extend it by adding mesh networking, multiple nodes, or cloud connectivity to build a full IoT data pipeline.
nRF24L01 modules send sensor data between two Arduino nodes — measure range, packet loss and transmission rate.
