LoRa Soil Sensor Field Node
Arduino LoRa Soil Sensor Node – Solar-Powered Field Monitoring 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.
Imagine monitoring your field’s soil moisture and temperature from anywhere without Wi‑Fi or cellular data. This solar-powered LoRa node reads two soil probes and a DS18B20 sensor, then uses the RA-02 module to send readings every 10 minutes over kilometres. It’s built for real-world agriculture: sturdy, weatherproof, and completely off-grid.
What You'll Build
You’ll assemble a standalone field node inside a waterproof enclosure. Once deployed, it measures soil moisture at two depths and ambient temperature, then transmits that data using long‑range LoRa. Powered by a 6V solar panel and two 18650 cells, it runs day and night without a single battery swap.
What You'll Learn
- Interfacing analog soil moisture sensors with Arduino for real‑world data acquisition
- Configuring and programming the RA-02 LoRa module for reliable long‑range transmission
- Designing a solar‑powered system with TP4056 charging and battery protection
- Deploying outdoor remote nodes with IP‑rated enclosures and antenna considerations

Who This Kit Is For
Ideal for CBSE Class 11–12 students building agriculture IoT projects, B.Tech ECE/EEE undergraduates prototyping for Smart India Hackathon, and ATL Tinkering Labs exploring wireless sensor networks. Also a perfect pick for hobbyists and rural innovators who want a field‑ready monitoring solution without recurring SIM charges.
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 launch the AI companion, or reach us via WhatsApp—both are preloaded with the exact pinouts, code snippets, and troubleshooting for this soil node kit.
How far can this LoRa node transmit?
In rural line‑of‑sight conditions, expect 3‑5 km with the included 433MHz antenna. Range drops with obstacles; our AI companion helps you optimise antenna placement and spreading factor for your site.
Is the enclosure truly waterproof for outdoor fields?
Yes, the IP65‑rated enclosure handles rain and dust. For prolonged submersion or heavy monsoon, we recommend sealing the cable gland with a dab of silicone—the AI guide shows you exactly where.
Can I log data to a cloud dashboard without Wi‑Fi?
The node transmits to any LoRa receiver; you can pair it with a gateway (like ESP32 + LoRa) and push data to ThingSpeak or Blynk. The companion walks you through a sample gateway setup.
Solar-powered Arduino with RA-02 LoRa transmits soil moisture and temperature from a field every 10 minutes.
