Core responsibilities

  • Designed and implemented an IoT-based smart agriculture system for continuous soil-health monitoring.
  • Integrated field probe telemetry for:
    • NPK nutrient sensing
    • soil pH
    • moisture
    • temperature
    • electrical conductivity
  • Built firmware in Embedded C (Arduino framework) on ESP32 for sensor acquisition and device-side communication.
  • Configured Raspberry Pi edge layer to aggregate, preprocess, and relay telemetry upstream.
  • Implemented complete data flow from soil sensor to cloud/dashboard for actionable agronomy recommendations.
  • Drove end-to-end development:
    • hardware component selection
    • interface and wiring bring-up
    • firmware development and integration
    • staged testing and troubleshooting

Location

Shillong, India

Impact

  • Shifted monitoring approach from periodic manual checks to near real-time telemetry.
  • Enabled precision fertilizer and irrigation decisions from live soil conditions.
  • Contributed to a deployable prototype aimed at higher yield, lower input cost, and more sustainable usage patterns.
