EXPANDED TECHNICAL DETAILS

Field Data Aquisition

This project builds a professional-grade environmental logger that can operate independently for months without PC connection.

  • MicroSD File System: The Arduino uses the SPI protocol to write sensor data into a .CSV file. The firmware includes a "File Sync" logic; it doesn't just write to memory, but calls flush() or closes the file periodically to ensure no data is lost in case of a power failure.
  • RTC Synchronization: Utilizing the DS1307 or DS3231 RTC chip, the system appends a high-precision timestamp to every reading. This allows researchers to correlate sensor spikes with specific times of day or weather events.

Electrical Efficiency

  • Power Optimization: For battery operation, the code can be integrated with "Sleep Modes," waking the Arduino only when the RTC triggers a timed interrupt, significantly extending the field life of the data logger.
