Solar-Powered Smart Bus Shelter with Lighting and Panic Button

Solar-Powered Smart Bus Shelter with Lighting and Panic Button is a tracking and emergency-alert prototype that can be demonstrated with PIR motion sensor, BH1750 or paired LDR light sensors, Momentary push button. 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 SIM800L/SIM7600 cellular module, Opto-isolated relay module. The important proof is repeatable input readings, decisions, output states, timestamps, and test results, not just a device that powers on.

Engineering profile

Tracking and emergency-alert prototype

Function Flow

Power and initialise

The regulated battery supply with protection starts the ESP32 development board and connected modules within their voltage and current requirements.

Acquire the input

PIR motion sensor + BH1750 or paired LDR light sensors + Momentary push button 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 presents the local result, while the communication link sends the corresponding event or reading.

Record and recover

The test sheet records the input, decision and output. On a fault, the system enters a defined safe state instead of silently continuing.

Guide

Build Scope Options

Basic prototype

Core demo using ESP32 development board, PIR motion sensor, BH1750 or paired LDR light sensors, Momentary push button 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 SIM800L/SIM7600 cellular module, Opto-isolated relay module from real or realistic PIR motion sensor, BH1750 or paired LDR light sensors, Momentary push button.
Stores or displays input readings, decisions, output states, timestamps, and test results as report evidence.
Demonstrates the main tracking and emergency-alert 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.

GSM and SMS features depend on SIM balance, signal coverage, and telco network availability.

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 SIM800L/SIM7600 cellular module, Opto-isolated relay module.

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.
Testing GSM/GPS only indoors and discovering signal issues during final demo.
