Private LoRaWAN Node with TTN Gateway Variant 2
Build a Private LoRaWAN Sensor Node: Arduino Nano & RA‑02 SX1278 for The Things Network
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 a field-ready sensor node that joins The Things Network entirely over-the-air, then pushes temperature, humidity and barometric pressure readings to a web console in real time. This kit turns that idea into a solder-together reality. With the Arduino Nano and RA‑02 LoRa SX1278 module, you will build a battery-powered LoRaWAN node that authenticates via OTAA, transmits encrypted payloads, and lets you watch decoded data appear in the TTN console — a complete private IoT pipeline you own end to end.
What You'll Build
By the end of the 12–15 hour build, you will have a sealed, autonomous LoRaWAN end device. It samples from a DHT22 and BMP280 every configurable interval, formats the readings into a compact byte payload, and sends them through a 433 MHz LoRa radio to any nearby TTN gateway. In the TTN console you will see live decoded temperature, humidity and pressure values, and you can forward those to cloud dashboards, spreadsheets, or alerting systems. The waterproof enclosure means the node can live outdoors, monitoring agriculture, remote infrastructure or campus micro-climates.
What You'll Learn
- Registering a LoRaWAN device in OTAA mode and obtaining session keys securely
- Configuring the RA‑02 (SX1278) with Arduino Nano for Indian 433 MHz spectrum
- Wiring and reading DHT22 / BMP280 sensors, then packing float values into IEEE‑754 or integer payloads
- Writing a JavaScript payload decoder for The Things Network console and testing uplinks live

Who This Kit Is For
This kit is built for the 25+ professional, researcher, or advanced student who already writes Arduino code and understands IoT basics. If you are a B.Tech / M.Tech candidate in ECE or CS working on a LoRaWAN capstone, a startup founder building a smart‑agriculture product, or an R&D engineer at an NIT, IIT or BITS Pilani lab, you will find every component rigorously matched. The learning path skips blinking LEDs and goes straight to over‑the‑air activation, payload formatting and long‑range field testing.
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 inside the box to open the AI companion trained on this specific kit. It can walk you through wiring, code upload, and TTN configuration step by step. If you prefer human help, WhatsApp support from our Bengaluru lab is available during Indian business hours.
The kit includes a 433 MHz antenna, but I thought Indian LoRaWAN uses 868 MHz. Will this work?
The RA‑02 module supports multiple bands. The included 433 MHz antenna is for immediate local testing and short‑range validation. For full 868 MHz deployment, you can easily swap in an 868 MHz antenna; the AI companion includes guidance on antenna selection and RF tuning for Indian licence‑free bands.
Do I need a LoRaWAN gateway to see data in The Things Network console?
Yes — a TTN‑connected gateway must be within range. If you don’t own one, you can use public community gateways (many are available in Indian cities) or build your own with a Raspberry Pi and concentrator. The kit’s build companion explains how to locate nearby gateways.
Can I add more sensors or change the transmission interval?
Absolutely. The included Arduino sketch is annotated to help you expand the payload. You can attach additional I2C sensors, alter the sleep‑and‑send interval, and update the TTN payload decoder accordingly. The AI companion can suggest code modifications for common sensors.
