Papan Tanda Jalan Raya dengan Solar/IoT
Papan Tanda Jalan Raya dengan Solar/IoT is an energy and power monitoring prototype that can be demonstrated with INA219 solar supply monitor. 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, Current-limited LED indicators. The important proof is repeatable Time-stamped database or data logger, not just a device that powers on.

A good version focuses on WiFi router/hotspot and dashboard service, Current-limited LED indicators using ESP32 development board, INA219 solar supply monitor, WiFi router/hotspot and dashboard service, with testing evidence for input calibration or baseline, response time, repeatability, power stability, communications failure, and safe-state behaviour.
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.
Engineering profile
Energy and power monitoring 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
INA219 solar supply monitor 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
Current-limited LED indicators 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.

IoT dashboard and data logging guide
Choose Blynk, Firebase, ThingsBoard or a custom dashboard with clearer evidence.
Electronics troubleshooting checklist before demo
Check wiring, power, sensors, alerts and backup demo flow before viva day.
Build Scope Options
Basic prototype
Core demo using ESP32 development board, INA219 solar supply monitor, 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, Current-limited LED indicators from real or realistic INA219 solar supply monitor.
- Stores or displays Time-stamped database or data logger as report evidence.
- Demonstrates the main energy and power monitoring 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.
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 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, Current-limited LED indicators.
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.
