IoT-Based Fish Market Cold Box Temperature Logger
IoT-Based Fish Market Cold Box Temperature Logger is a water monitoring and control prototype that can be demonstrated with water level, pH, TDS, turbidity, temperature, flow, or leak sensor reading. A realistic FYP outcome is a working prototype where the controller compares readings against safe thresholds and decides whether to alert or activate a pump/valve, then produces dashboard reading, warning alert, pump/valve control, LCD status, or testing log. The important proof is repeatable sensor readings, threshold values, calibration notes, alert events, and control status, not just a device that powers on.
Project Snapshot
Quick Summary
IoT-Based Fish Market Cold Box Temperature Logger is a water monitoring and control prototype idea for students who need a working demo with water level, pH, TDS, turbidity, temperature, flow, or leak sensor reading. A good version focuses on dashboard reading, warning alert, pump/valve control, LCD status, or testing log using Water sensor, ESP32/Arduino, Relay/pump, with testing evidence for sensor calibration, wet-environment protection, threshold response, and repeat readings.
Difficulty
Intermediate
Time Required
4-8 weeks for wiring, coding, dashboard/app integration and repeated testing
Cost
No fixed price. Cost depends on selected controller, sensors, communication modules, casing, dashboard/app features and documentation scope.
Components
DHT22, ESP32, Food, Logger
How This Project Works
The prototype collects water level, pH, TDS, turbidity, temperature, flow, or leak sensor reading using the selected modules.
The controller performs the controller compares readings against safe thresholds and decides whether to alert or activate a pump/valve.
The result is shown through dashboard reading, warning alert, pump/valve control, LCD status, or testing log.
Testing records sensor calibration, wet-environment protection, threshold response, and repeat readings so the demo can be explained during viva.

Build Scope Options
Basic prototype
Core demo using Water sensor, ESP32/Arduino, Relay/pump, Dashboard or display 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 dashboard reading, warning alert, pump/valve control, LCD status, or testing log from real or realistic water level, pH, TDS, turbidity, temperature, flow, or leak sensor reading.
- Stores or displays sensor readings, threshold values, calibration notes, alert events, and control status as report evidence.
- Demonstrates the main water monitoring and control prototype workflow end to end.
- Includes a clear test scenario for sensor calibration, wet-environment protection, threshold response, and repeat readings.
Accuracy & Limitations
This is realistic for FYP when the scope stays controlled: Use controlled water samples and labelled test scenarios instead of claiming laboratory-grade accuracy.
Prototype reliability depends on correct wiring, stable power supply, and proper module selection.
Sensor readings can vary with placement, calibration, environment, and demo conditions.
Validation & Testing Plan
Run repeated tests under controlled demo conditions and record readings or status changes.
Verify sensor calibration, wet-environment protection, threshold response, and repeat readings 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 dashboard reading, warning alert, pump/valve control, LCD status, or testing log.
Common Mistakes
- Choosing a scope that is too large for the available FYP timeline.
- Use controlled water samples and labelled test scenarios instead of claiming laboratory-grade accuracy.
- 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.
