Soil Carbon Proxy Monitoring Network Variant 29 Kit with ESP32 + LoRa
Build a Multi-Depth Soil Carbon Proxy Monitoring Network with ESP32 + LoRa
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Deploy five autonomous sensor nodes at different soil depths to measure TDS EC and turbidity—proxies that correlate strongly with soil organic carbon. Data streams over a LoRa mesh to a central ESP32 gateway, logging every reading with precise timestamps. Whether you’re quantifying sequestration for carbon credits, optimizing regenerative agriculture, or running a longitudinal field study, this kit hands you a research-grade network in a box.
What You'll Build
A fully operational, solar-ready soil monitoring network with five sub-surface sensor pods transmitting turbidity and conductivity readings to a central logger. You’ll assemble, calibrate, and deploy a system that charts organic carbon proxy trends across depth and time, ready for integration into precision farming dashboards or carbon verification reports.
What You'll Learn
- Calibrate TDS EC sensors against known soil carbon samples to establish field-specific proxy curves
- Program LoRa mesh communication between multiple Arduino nodes and an ESP32 gateway
- Design waterproof enclosures for long-term in-soil sensor deployment
- Log and timestamp sensor data onto microSD for offline carbon proxy analysis

Who This Kit Is For
Agritech researchers and graduate students in environmental engineering, precision agriculture startups building carbon credit verification tools, and faculty guiding Smart India Hackathon teams on soil health IoT projects. Ideal for those with prior Arduino experience ready to deploy a multi-node sensor network in real field conditions—common in B.Tech ECE/EEE final year projects and institutional climate studies at IIT, NIT, VIT, and BITS campuses.
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.

How do I calibrate the TDS EC and turbidity sensors for my soil's organic carbon content?
The AI companion guides you through a simple field calibration process using local soil samples sent to a lab for reference carbon measurement, building a custom proxy curve for your location.
What is the typical LoRa transmission range between sensor nodes and the gateway in agricultural fields?
With the included 433MHz antennas and line-of-sight, expect 1-2 km; through moderate crop canopy, 500-800 m. The mesh network extends coverage by relaying through nearest nodes.
Can I use this kit to generate data for carbon credit verification standards?
Yes, the logged depth-resolved proxy data can be correlated with laboratory carbon measurements to estimate soil organic carbon stocks, supporting methodologies like VCS VM0042, but final verification requires accredited lab testing.
TDS EC + optical turbidity at multiple soil depths correlate with organic carbon content. LoRa uploads data.
