LoRa Farm Sensor Array Kit - 8-Node Soil Monitoring with GPS Dashboard
Build an 8-Node LoRa Farm Sensor Array with ESP32 Gateway & GPS Crop Health Dashboard
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 walking your fields with a tablet displaying real-time soil moisture and temperature readings from eight self-sustaining nodes, plotted over a GPS map of your land. You'll see exactly where crops are stressed and where to irrigate next. This kit transforms that vision into a fully functional LoRa-based farm monitoring system-no cloud subscription required.
What You'll Build
A solar-powered wireless sensor network covering up to several acres, with 8 nodes each reporting moisture and temperature via LoRa to a central ESP32 gateway. The gateway runs a local web dashboard that plots each node's GPS coordinates and overlays color-coded crop health indicators. You can place nodes in the field, power them with solar, and monitor data from your phone or laptop without internet connectivity.
What You'll Learn
- Deploy a long-range LoRa mesh network with custom addressing and reliable data transmission.
- Interface multiple soil moisture and temperature sensors with Arduino Nano and calibrate readings for Indian soil types.
- Configure an ESP32 as a LoRa receiver and web server to display real-time sensor data and GPS coordinates.
- Build a solar-powered battery management system using TP4056 and 18650 cells for continuous remote operation.

Who This Kit Is For
This advanced kit suits B.Tech ECE/EEE students building LoRa-based precision agriculture capstone projects, Smart India Hackathon teams tackling farm digitization challenges, and early-stage Agritech founders prototyping wireless sensor networks. It's also ideal for researchers at IIT, NIT, VIT, or BITS Pilani exploring sustainable remote monitoring solutions for Indian farms.
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?
The kit includes a QR code linking to our AI companion, which offers step-by-step diagnostics, wiring checks, and firmware debugging for every node. WhatsApp backup is also available-just send us a photo of your setup.
Can I extend the network beyond 8 nodes?
Yes. The LoRa addressing scheme taught in the build supports up to 255 nodes. After you master the base system, you can add more nodes by flashing the same firmware and assigning new addresses.
Do the sensor nodes need internet connectivity?
No. Nodes communicate via LoRa to the gateway. Only the gateway can optionally connect to Wi-Fi for cloud integration, but the local dashboard and crop health overlays function completely offline in the field.
How accurate is the soil moisture sensor for Indian soils?
The included capacitive sensors are corrosion-free and output relative moisture levels. The build companion provides a calibration guide optimized for lateritic, alluvial, and black cotton soils commonly found across India, along with temperature compensation routines.
Eight soil nodes send moisture, temp and GPS to a LoRa gateway. Dashboard maps sensor positions with crop health overlays.
