Precision Agriculture Soil Moisture Sensor Kit – Arduino Mega 2560 with 10GHz Microwave Radar

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

Assemble a professional-grade 10GHz Doppler radar system that measures soil moisture by detecting changes in the dielectric constant of the ground itself. This kit provides everything you need to build a solar-powered field station that logs volumetric water content data directly to a MicroSD card—ready to integrate into smart irrigation, climate research, or environmental monitoring projects. The moment you power it on, you step into the world of precision agriculture sensing with real radar physics behind every reading.

What You'll Build

You will assemble a complete microwave backscatter sensor node that uses two RCWL-0516 Doppler modules to measure how soil reflectivity changes with moisture at 10GHz. The system compensates for temperature variations with a waterproof DS18B20 probe, time‑stamps every measurement with a DS3231 real‑time clock, and writes records to a MicroSD card for offline analysis. The entire unit is housed in a waterproof enclosure and runs off a solar panel recharging two 18650 cells—a truly field‑deployable instrument that works unattended for weeks.

What You'll Learn

• How microwave backscattering correlates with soil volumetric water content and why 10GHz works for non‑contact sensing
• Interfacing an Arduino Mega 2560 with multiple sensors simultaneously—radar modules, DS18B20, DS3231 RTC, and an OLED display
• Designing a solar‑powered, off‑grid data logging system using 18650 batteries, a TP4056 charging module, and a buck converter
• Soldering components onto a prototype PCB and weatherproofing the enclosure for outdoor agricultural deployment
