LoRaWAN OTAA Network Join Kit – Build an Arduino LoRa Sensor Node That Sends Data to ChirpStack

Every component needed to build a LoRaWAN OTAA sensor node, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

You’ll assemble a compact sensor node with DHT22 and BMP280 sensors, power it with a LiPo battery, and program the Arduino to perform an Over-The-Air Activation (OTAA) join on a ChirpStack LoRaWAN server. Once authenticated, your live temperature, humidity, and pressure readings will stream to a web dashboard — exactly as IoT deployments work in smart agriculture and industry.

What You'll Build

By the end of this project, you’ll have a functional LoRaWAN end device transmitting environmental data over long range to a ChirpStack application server. The node is built on a prototyping board, powered by a rechargeable LiPo cell, and its data packets are decoded using the ChirpStack web interface — giving you a complete IoT pipeline from sensor to cloud.

What You'll Learn

• LoRaWAN Over-The-Air Activation (OTAA) and key provisioning
• Interfacing RA-02 LoRa module with Arduino Nano using the LMIC library
• Reading environmental sensors (DHT22, BMP280) and encoding data for LoRaWAN
• Deploying and decoding payloads on a ChirpStack application server
