IoT-Based Smart Curtain Control with Light Sensor

IoT-Based Smart Curtain Control with Light Sensor is an iot monitoring and automation prototype that can be demonstrated with BH1750 or paired LDR light sensors. A realistic FYP outcome is a working prototype with this processing path: Reads sensors, applies control logic and provides WiFi/Bluetooth when required; Converts readings into a documented state, threshold or event. The result is delivered through WiFi router/hotspot and dashboard service, Opto-isolated relay module, Servo motor. The important proof is repeatable Time-stamped database or data logger, not just a device that powers on.

Engineering profile

IoT monitoring and automation prototype

Function Flow

Power and initialise

The regulated 5 v supply with common ground starts the ESP32 development board and connected modules within their voltage and current requirements.

Acquire the input

BH1750 or paired LDR light sensors supplies the project measurement, identity or trigger.

Validate the signal

Firmware rejects missing or implausible samples and applies calibration, debounce or averaging appropriate to the module.

Make the decision

The controller compares the validated value with the documented threshold, authorisation rule or operating state.

Act and communicate

Opto-isolated relay module + Servo motor presents the local result, while the communication link sends the corresponding event or reading.

Record and recover

The logger stores the input, decision, output and timestamp. On a fault, the system enters a defined safe state instead of silently continuing.

Build Scope Options

Basic prototype

Core demo using ESP32 development board, BH1750 or paired LDR light sensors, WiFi router/hotspot and dashboard service, Time-stamped database or data logger 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 WiFi router/hotspot and dashboard service, Opto-isolated relay module, Servo motor from real or realistic BH1750 or paired LDR light sensors.
Stores or displays Time-stamped database or data logger as report evidence.
Demonstrates the main iot monitoring and automation prototype workflow end to end.
Includes a clear test scenario for input calibration or baseline, response time, repeatability, power stability, communications failure, and safe-state behaviour.

Accuracy & Limitations

This is realistic for FYP when the scope stays controlled: Validate the input-to-controller-to-output path with safe bench tests before adding cloud features, casing, or extra modules.

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 input calibration or baseline, response time, repeatability, power stability, communications failure, and safe-state behaviour 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 WiFi router/hotspot and dashboard service, Opto-isolated relay module, Servo motor.

Common Mistakes

Choosing a scope that is too large for the available FYP timeline.
Validate the input-to-controller-to-output path with safe bench tests before adding cloud features, casing, or extra modules.
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.
