Overview

Built SoilSync IoT, an end-to-end smart agriculture prototype for continuous soil-health monitoring and data-driven fertilizer decisions.

The system replaces periodic manual checks with live field telemetry for:

  • NPK (nitrogen, phosphorus, potassium)
  • soil moisture
  • soil temperature
  • pH
  • electrical conductivity (EC)

Implementation

  • Integrated multi-parameter NPK probe (ISE-based) with ESP32 acquisition node.
  • Developed embedded firmware in C (Arduino framework) for sensor polling and packetized transmission.
  • Used Raspberry Pi as edge controller for aggregation, preprocessing, and uplink orchestration.
  • Added wireless pipeline for cloud upload and remote dashboard/mobile visibility.
  • Defined practical architecture flow:
    • sensing in soil (probe)
    • local acquisition (ESP32)
    • edge handling (Raspberry Pi)
    • wireless transport (IoT modem)
    • cloud-backed insights for the end user
  • Worked across full bring-up lifecycle:
    • component selection
    • bench validation
    • firmware integration
    • field-oriented test runs

Real-world use cases

  • Precision fertilization using live nutrient levels
  • Smart irrigation decisions using moisture trends
  • Continuous soil quality monitoring over time
  • Data capture for field trials and agriculture research

Outcome and impact

Delivered a stable end-to-end prototype for agricultural telemetry and decision support.

Expected operational impact from pilot assumptions:

  • up to 20% crop-yield improvement
  • up to 30% fertilizer-cost reduction
  • reduced chemical overuse and runoff through targeted input application
