Drone GPS Navigator Kit with Arduino Mega + LED
Drone GPS Navigator Kit with Arduino Mega — Measure Implement Draft Force for Precision Agriculture
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Agricultural drones need to do more than fly — they must feel the land. This kit lets you build a payload that mounts a 50kg strain gauge load cell directly to a three-point hitch, measuring the draft force an implement exerts on the soil. That force reading, timestamped by a DS3231 RTC and geo-stamped by a NEO-6M GPS, writes to a MicroSD card. It is the foundation of variable-rate tillage, soil compaction mapping, and field-scale implement analytics.
What You'll Build
You will assemble a sealed, drone-mountable data acquisition unit that captures implement draft force in real time. The 0.96-inch OLED shows live load values and GPS fix status during flight. Back on the ground, you pull the SD card and get a CSV with latitude, longitude, UTC time, and force in kilograms — ready for QGIS, Excel, or custom Python analysis. The waterproof enclosure and 12V truck PSU mean it survives dust, vibration, and long field days.
What You'll Learn
- Conditioning a strain gauge signal through an HX711 24-bit ADC and calibrating zero-offset and scale factor for accurate kilogram readings
- Parsing NMEA sentences from a NEO-6M GPS over UART and synchronizing readings with a DS3231 real-time clock for microsecond-accurate timestamps
- Writing structured CSV data to a MicroSD module with SPI, handling file creation, buffer flushing, and safe removal
- Designing a 12V power distribution bus on a PCB prototype board with filtering capacitors to keep sensor noise away from the Arduino Mega

Who This Kit Is For
This kit is built for B.Tech ECE and EEE students taking on Smart India Hackathon agriculture challenges, where sensor fusion and field data logging decide podium finishes. It fits ATL Tinkering Lab mentors guiding advanced student groups into AgriTech prototyping. Researchers at IIT, NIT, VIT, or BITS Pilani working on precision farming testbeds will find the draft force measurement immediately useful for validating tractor-implement interaction models.
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 enclosure to start a session with our AI build companion, which has been trained on every wiring detail and calibration step for this specific kit. For issues that need a human touch, WhatsApp support from our Bengaluru lab responds within hours.
How do I mount the load cell to a drone's three-point hitch?
The 50kg load cell mounts in-line between the hitch top-link bracket and the implement drawbar using M8 bolts through its strain points. The kit includes a waterproof enclosure with a cable gland so the HX711 and Mega stay protected while only the load cell body is exposed.
Can I power this from a drone's LiPo instead of the truck PSU?
The included 12V truck PSU accepts a wide 8-36V input, so you can feed it from a 4S or 6S LiPo on the drone's power distribution board. The PSU then provides clean 12V to the Mega and sensors, filtering motor noise that would otherwise corrupt the HX711 readings.
Is the logged GPS data compatible with standard GIS software?
Yes. The CSV format written to the SD card includes standard decimal-degree latitude and longitude fields, making drag-and-drop import into QGIS, ArcGIS, or Google Earth straightforward. The DS3231 timestamps follow ISO 8601, so time-series tools will parse them without reformatting.
