Project overview

25-26J-016 | CSNE

One smart pipeline for export-ready pineapple decisions.

PineSense brings forecasting, machine vision and IoT control into one workflow so farmers and exporters can plan harvests, inspect fruit and separate grades with less manual guesswork.

Capture Predict Grade Sort
01

Harvest Forecasting

Uses weight, size and field records to support supply planning.

02

Ripeness Detection

Classifies unripe, ripe and overripe fruit from camera images.

03

Defect Grading

Detects black spots, holes and fungus to assign export grades.

04

IoT Dashboard

Connects ESP32, sensors, MQTT and monitoring interfaces.

Product concept

From field data to automated export sorting.

Cameras, load cells and sensors capture fruit condition while AI models classify ripeness, detect defects and convert measurements into export-focused grades and planning insights.

01 - Domain

Research foundation behind PineSense.

The research focuses on reducing export losses through objective fruit assessment, real-time sensing and automated grading support.

Literature Survey

Existing work on fruit grading, YOLO-based object detection, precision agriculture and IoT monitoring guided the system design.

Research Gap

Current pineapple workflows are manual and fragmented, with no single system for harvest prediction, ripeness detection, defect grading and farm monitoring.

Research Problem

How can AI and IoT be combined to produce consistent export-quality pineapple decisions while reducing post-harvest losses?

Research Objectives

Develop an integrated system for yield forecasting, ripeness classification, defect detection, quality grading and real-time dashboard monitoring.

Methodology

Collect image, weight and sensor data, train YOLO-based models, run edge/device workflows and send results through MQTT to a monitoring dashboard.

Technologies Used

YOLO11, Python inference workflows, ESP32 firmware, MQTT, Node-RED concepts, load cells, cameras, gas sensors and dashboard interfaces support the prototype.

02 - Milestones

Research progress and implementation timeline.

Milestones track the proposal, model development, IoT integration and final research delivery for the export-quality pineapple system.
