Q: How does the board keep different temperature zones in one cabinet?
A: Four independent NTC sensor channels feed zone-specific control loops, so chilled, frozen and ambient sections each hold their set points while one Android interface manages pickup for all doors.
Q: What happens if a cooling zone drifts out of range?
A: The board raises over-temperature alarms immediately by SMS, email and app push, logs the event locally and to the cloud, and can lock out affected doors until temperatures recover.
Q: Can temperature records be exported for audits?
A: Yes. Logs are stored on eMMC and synchronized to the cloud CMS, exportable as CSV reports covering time, zone and temperature for cold-chain compliance audits.
Q: Does the board work inside the freezer compartment?
A: The extended-temperature variant is rated for -30°C to 70°C operation, suitable for freezer-side mounting with conformal coating against condensation.
Q: Is compressor control compatible with common refrigeration units?
A: PWM and relay outputs cover mainstream compressor and fan units, and wiring diagrams plus protocol documentation are provided for integration with existing cooling systems.
