ESP32 Private LoRaWAN Node
Build a Private LoRaWAN Node with ESP32 – Chirpstack OTAA & Sensor Data Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Take your IoT skills from prototype to production-grade infrastructure. This kit lets you build a battery-operated, waterproof LoRaWAN node that captures temperature, humidity, and barometric pressure from a DHT22 and BMP280, then transmits the data securely over kilometres to your own Chirpstack server using Over-the-Air Activation. Whether you're designing a campus weather network, a precision agriculture sensor array, or a Smart India Hackathon entry, you'll leave with a deployable device that stores decoded sensor records in a database.
What You'll Build
A fully enclosed, LiPo-powered ESP32 end node that wakes from deep sleep every few minutes, reads two environmental sensors, crafts a LoRaWAN uplink, and joins a Chirpstack server via OTAA. The server decodes the payload and pushes structured data to a database of your choice. You'll learn to mount the antenna correctly, seal the enclosure for outdoor use, and monitor battery voltage remotely.
What You'll Learn
- Provision a LoRaWAN device using OTAA on Chirpstack, generating DevEUI, AppKey, and AppEUI
- Interface DHT22 (One-Wire) and BMP280 (I2C) sensors with ESP32 and handle multiple sensor readings in a single uplink
- Optimise ESP32 deep sleep timers and LiPo charging with the TP4056 module for months-long battery life
- Waterproof the enclosure, mount the 433MHz antenna with RF-safe sealing, and install the node in the field

Who This Kit Is For
Built for B.Tech ECE/EEE students tackling IoT capstone projects, Smart India Hackathon teams prototyping low-power sensor networks, and researchers at IITs, NITs, VIT, or BITS setting up campus-wide LoRaWAN deployments. If you're comfortable soldering and have programmed an Arduino or ESP32 before, this kit bridges the gap to carrier-grade IoT infrastructure.
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 chat with our AI build companion, which gives circuit diagrams, code snippets, and troubleshooting steps specific to this kit. For persistent issues, message us on WhatsApp for engineer-led support.
Do I need a separate LoRaWAN gateway?
Yes, this kit is an end node. You'll need a LoRaWAN gateway like the RAK7258, a multichannel concentrator, or a DIY ESP32 gateway to receive the uplinks. We include full Chirpstack setup guides for popular gateways, so you can have your own private network running in hours.
Can I power this node with a solar panel?
Absolutely. The TP4056 charging module accepts a 5V micro-USB input, making it easy to connect a small solar panel. Combined with ESP32 deep sleep, the node can run indefinitely outdoors without manual recharging.
What is OTAA and why use it instead of ABP?
Over-the-Air Activation (OTAA) dynamically generates session keys during each join, which prevents replay attacks and makes your deployment far more secure than Activation by Personalisation (ABP). The kit walks you through registering your device on Chirpstack with DevEUI, AppKey, and AppEUI, then shows how the network server issues fresh keys after every re-join.
RA-02 LoRa on ESP32 joins a Chirpstack LoRaWAN server using OTAA. Sensor data decoded and stored in DB.
