IoT-Based Classroom Air Quality and Occupancy Monitoring System
IoT-Based Classroom Air Quality and Occupancy Monitoring System is a camera and visual-monitoring prototype that can be demonstrated with camera image, video frame, snapshot, or detected motion event. A realistic FYP outcome is a working prototype where the controller or Raspberry Pi captures images and applies simple image processing or event detection, then produces captured evidence, recognition result, alert notification, or dashboard image log. The important proof is repeatable image samples, detection result, timestamp, confidence/condition notes, and event history, not just a device that powers on.
Project Snapshot
Quick Summary
IoT-Based Classroom Air Quality and Occupancy Monitoring System is a camera and visual-monitoring prototype idea for students who need a working demo with camera image, video frame, snapshot, or detected motion event. A good version focuses on captured evidence, recognition result, alert notification, or dashboard image log using Camera, ESP32-CAM/Raspberry Pi, OpenCV or dashboard, with testing evidence for lighting, camera angle, dataset examples, false detections, and repeatable demo scenes.
Difficulty
Advanced
Time Required
8-12 weeks including component testing, integration, calibration and demo preparation
Cost
No fixed price. Cost depends on selected controller, sensors, communication modules, casing, dashboard/app features and documentation scope.
Components
IoT, Air Quality, PIR, ESP32
How This Project Works
The prototype collects camera image, video frame, snapshot, or detected motion event using the selected modules.
The controller performs the controller or Raspberry Pi captures images and applies simple image processing or event detection.
The result is shown through captured evidence, recognition result, alert notification, or dashboard image log.
Testing records lighting, camera angle, dataset examples, false detections, and repeatable demo scenes so the demo can be explained during viva.

Build Scope Options
Basic prototype
Core demo using Camera, ESP32-CAM/Raspberry Pi, OpenCV or dashboard, Storage/alert with visible input and output response.
Intermediate prototype
Adds dashboard/database logging, alerts, calibration notes, and cleaner wiring for reliable demonstration.
Advanced prototype
Adds casing, mobile/cloud features, multi-node setup, image processing, maps, or reporting depending on scope.
Expected Demo Outcome
- Shows captured evidence, recognition result, alert notification, or dashboard image log from real or realistic camera image, video frame, snapshot, or detected motion event.
- Stores or displays image samples, detection result, timestamp, confidence/condition notes, and event history as report evidence.
- Demonstrates the main camera and visual-monitoring prototype workflow end to end.
- Includes a clear test scenario for lighting, camera angle, dataset examples, false detections, and repeatable demo scenes.
Accuracy & Limitations
This is realistic for FYP when the scope stays controlled: Limit the first version to one visual task and controlled lighting before adding advanced AI claims.
Prototype reliability depends on correct wiring, stable power supply, and proper module selection.
Sensor readings can vary with placement, calibration, environment, and demo conditions.
Low-cost gas sensors are suitable for relative detection and alerts, not laboratory-grade gas concentration measurement.
IoT demos depend on stable WiFi, hotspot, or internet access unless an offline backup mode is prepared.
Validation & Testing Plan
Run repeated tests under controlled demo conditions and record readings or status changes.
Verify lighting, camera angle, dataset examples, false detections, and repeatable demo scenes before adding extra features.
Capture photos, dashboard screenshots, serial logs, or database entries as testing evidence.
Document sensor/module limits honestly so the report does not overclaim industrial accuracy.
Troubleshooting
If readings are unstable, test the sensor separately before connecting the dashboard or app.
If the module resets, check power supply, common ground, loose jumper wires, and current requirements.
If alerts or cloud updates fail, test WiFi, hotspot, SIM balance, API token, and internet connection early.
If the demo is hard to explain, focus on one repeatable workflow for captured evidence, recognition result, alert notification, or dashboard image log.
Common Mistakes
- Choosing a scope that is too large for the available FYP timeline.
- Limit the first version to one visual task and controlled lighting before adding advanced AI claims.
- Writing objectives that do not match the actual prototype or software demo.
- Preparing no backup demo flow for viva day.
- Using weak power supply, loose jumper wires, or unprotected sensors during demonstration.
- Skipping calibration or test readings before presenting results.
