ESP32 LoRa Sensor Node Kit: Build a 1km Range Environmental Transmitter Without WiFi or Cellular

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Equip your farm, greenhouse, or remote monitoring station with a wireless sensor node that transmits real-time temperature and humidity data up to a kilometre away. No WiFi, no SIM card - just a robust LoRa link from the ESP32 and RA-02 module to your gateway. You'll have a weatherproof sensing unit running on a USB power bank, ideal for agricultural microclimate tracking, smart cities, and hackathon prototypes.

What You'll Build

A fully functional LoRa sensor node that reads DHT22 temperature and humidity every minute and sends the data packets over 433MHz LoRa to any compatible receiver. Mount it on a pole in your field, and instantly view environmental trends on a dashboard connected to the gateway. The included breadboard and jumper wires keep everything solderless, so you can iterate quickly.

What You'll Learn

• Configuring the ESP32 to read sensor data using the DHT22 library with precise timing
• Initializing the RA-02 LoRa module (SX1278) over SPI and setting frequency, bandwidth, and spreading factor
• Structuring point-to-point LoRa packets with device ID, sensor values, and checksum
• Decoding received data on a gateway ESP32 and forwarding it via serial monitor or MQTT for cloud logging

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is built for intermediate makers, CBSE Class 11-12 students developing IoT projects, and B.Tech ECE/EEE students prototyping for Smart India Hackathon. It's equally relevant for ATL Tinkering Lab mentors who need a wireless sensor module that works beyond WiFi range, and for agriculturists deploying microclimate stations with minimal 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.
