7.1 Settings

Core Settings (stored on startup for diagnostics)

All key system parameters are saved at each startup in a separate log file.
This allows full traceability of configuration during deployments and troubleshooting.

Sampler mode

EEPROM0

Defines the overall operating mode of the SmartSampler.
Primarily used to enable predefined workflows for specific modules.

Notes

• Mode 0 allows full flexibility and is recommended for custom setups
• Other modes provide predefined configurations tailored to specific applications
• Additional modes may be added in future firmware versions
• The selected mode is logged at each startup for diagnostics and traceability

Interval time

EEPROM2 (minutes)

Defines the main sampling interval.

• Unit: minutes
• Used for scheduling sampling cycles
• Example:
  • Value 15 → sampling every 15 minutes

Sensor read interval

EEPROM146 (seconds)

Defines how often sensors are read.

• Unit: seconds
• Independent from saving interval
• Allows high-frequency monitoring without excessive data storage

Sensor save interval

EEPROM160 (seconds)

Defines how often sensor readings are stored.

• Unit: seconds
• Must be ≥ sensor read interval
• Used to reduce data volume while maintaining resolution

System configuration

EEPROM180 (bitmask)

System-wide configuration stored as a boolean bit table.

Each feature is represented by a single bit (power-of-two value):

• The stored value is the sum of all active options
• Example:
  • Disable LED + Power down sensors + Auto start
    → 1 + 4 + 32 = 37

Notes for diagnostics

• All values are logged at system startup
• Allows reconstruction of system state during:
  • field deployments
  • unexpected behavior
  • power cycles or resets
• Bitmask configuration enables compact storage and easy extension
