FAQ

The sensor is factory-calibrated for accuracy and generally requires no frequent recalibration. However, for long-term projects or demanding applications, it is advisable to perform annual calibration and gently clean the housing to remove dust buildup.

Yes. Multiple RS485 sensors can be connected on the same communication bus, allowing users to monitor multiple zones simultaneously through a central monitoring platform or data logger.

Check for loose wiring, poor ventilation, or interference from nearby electronic equipment. Cleaning the sensor housing and ensuring stable power supply often restores normal operation.
