ECE Lab Kit 21 LoRa Long Range Sensor Node
Build a LoRa Long-Range Sensor Node with Arduino Nano – ECE Lab Kit 21
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transmit temperature and humidity data from a sensor node to a gateway node and systematically vary the LoRa spreading factor to understand the trade-off between range and transmission power. This intermediate-level kit designed for ECE students and lab classrooms puts theory into practice with a real RF link budget experiment. You'll build a complete wireless sensor network, collect empirical range data, and compare it with theoretical predictions.
What You'll Build
By the end of this project, you'll have two Arduino Nano-based nodes communicating over 433 MHz LoRa. The sensor node reads the DHT22 and sends the data to the gateway node which displays it on the OLED. You'll map the reliable communication range at different LoRa parameter settings, giving you empirical data to compare with the theoretical link budget. The result is a portable, battery-powered sensor unit that demonstrates long-range IoT communication firsthand.
What You'll Learn
- Configure and program the RA-02 LoRa module using Arduino IDE
- Interface DHT22 temperature/humidity sensor and parse digital output
- Display real-time data on a 0.96-inch OLED screen via I2C
- Measure the effect of LoRa spreading factor and transmission power on range and packet reliability

Who This Kit Is For
This kit is ideal for B.Tech ECE/EEE students working on wireless communication lab assignments, CBSE Class 12 science students preparing for Smart India Hackathon, and ATL Tinkering Lab mentors guiding data telemetry projects. It's also used by final-year engineering students at IITs, NITs, and VIT for their capstone IoT projects.
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?
The included AI companion provides instant troubleshooting and step-by-step code. If you need human help, our WhatsApp support responds within a few hours.
Do I need any external tools or soldering?
No soldering is required. The kit uses two half breadboards and pre-cut jumper wires, so you only need a computer with the Arduino IDE and a USB port.
Can I increase the range beyond the initial setup?
Yes, the experiment is designed to test different LoRa parameters like spreading factor and bandwidth. With line-of-sight and optimum settings, ranges over 1 km are achievable, and you can measure that empirically.
How do I power the sensor node in the field?
The sensor node runs on a single 18650 Li-ion cell with a holder, making it fully portable. You can later add a solar panel or use a power bank for extended tests.
RA-02 LoRa module sends DHT22 data from sensor node to gateway node — measure range vs transmission power.
