| Measurement Principle | LiDAR (Light Detection and Ranging) - ToF | Non-contact distance measurement using laser light. |
| Sensor Component | VL53L0X | Integrated Time-of-Flight sensor module. |
| Measurement Target | Distance from Sensor to Water Surface | The difference between the sensor's mounting height and measured distance yields the water level. |
| Data Acquisition Cycle | 5 Minute Interval | The system performs a full reading, averaging, and comparison every 5 minutes. |
| Averaging Routine | 10 Readings per Cycle | 10 individual measurements are taken within each 5-minute window and averaged. |
| Comparison Logic | Current Average vs. Previous Transmitted Reading | Used to detect significant changes before data transmission. |
| Communication | GSM (Global System for Mobile Communications) | Used for wireless transmission of processed data. |
| Data Output | Distance/Level in mm or cm | Raw sensor distance is processed into water level and sent to the cloud. |
| Power Source | DC Battery / Solar Panel (Assumed) | Solar power is ideal for remote operation. |
| Enclosure/Mounting | Weather-resistant, Secure Mounting Bracket | Sensor must be mounted above maximum water level, pointing downward. |
