LoRa Long Range Sensor Telemetry
Build a 1km+ LoRa Sensor Telemetry Network with ESP32 Gateway — No WiFi or Cellular Needed at the Edge
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
In farms that stretch for acres, warehouses that block WiFi, or pipelines that run for kilometres, you don't have the luxury of a constant internet connection at every sensor point. This kit lets you deploy two battery-powered LoRa nodes that transmit temperature, humidity, and pressure data over 1km without relying on WiFi or a cellular network. One ESP32 acts as a gateway, picking up the LoRa packets and forwarding them straight to your cloud dashboard — perfect for remote environmental monitoring, precision agriculture, or industrial sensor telemetry from a central location.
What You'll Build
You'll assemble two independent LoRa transmitter nodes, each with its own DHT22 sensor and a shared BMP280 on one node, plus an OLED display to view readings locally. The nodes send sensor data via SX1278 radio to a receiver ESP32 that logs, displays, and pushes the payload to a cloud endpoint over WiFi. By the end, you'll have a fully functional, long-range telemetry network that you can scale with additional nodes, all without writing a single HTTP request on the sensor side.
What You'll Learn
- Configure and range-test SX1278 LoRa modules for reliable 1km+ communication in Indian outdoor conditions
- Integrate DHT22 and BMP280 sensors into battery-optimised ESP32 nodes with deep sleep
- Design a multi-node star network with collision avoidance using simple LoRa packet addressing
- Build an ESP32 gateway that receives LoRa frames and uploads structured JSON to a cloud platform like ThingSpeak or Firebase

Who This Kit Is For
This advanced kit is built for B.Tech ECE/EEE students tackling Smart India Hackathon challenges, IoT researchers at IITs and NITs prototyping low-power wide-area networks, and agritech or industrial automation engineers who need to deploy long-range sensor nodes without relying on cellular modules. If you're already comfortable with Arduino IDE, soldering, and basic power management and want to move beyond single-board WiFi projects, you'll find the right depth here.
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?
Open the AI companion from the QR code. It knows this exact kit's wiring, code, and common pitfalls. If you need a human, message us on WhatsApp — we typically reply within a few hours.
Can I increase the range beyond 1km?
Yes, the SX1278 can reach 3-5km in clear line of sight with the right antenna and spreading factor settings. The AI companion includes a range-tuning guide specific to Indian terrain.
Do I need a LoRaWAN network server?
No, this project uses point-to-point LoRa communication. The gateway receives raw packets directly and forwards them to the cloud — no The Things Network or gateway software required.
Can I add more sensor nodes later?
Absolutely. The packet protocol is simple to extend. You can duplicate a node circuit, assign a new address, and the gateway will handle additional IDs without code changes on the receiver side.
Two LoRa nodes send sensor data 1km+ range without WiFi. Gateway uploads to cloud via ESP32 WiFi.
