• Easy Installation and Operation: This refrigerator door alarm sensor is compact and portable, making installation and operation very convenient. Its alarm trigger has clear thresholds: a low-volume buzzer will sound when the gap in the door exceeds 1.8 cm on a metal surface or 3 cm on a wooden/plastic surface. This provides timely warnings of abnormalities and effectively prevents accidental triggering of irrelevant alarms, making it suitable for various usage scenarios.
• Refrigerator Door Ding-Dong Alert Mode (press the SET button twice for two beeps): When the refrigerator door is opened, causing the fridge alarm door open to separate from the magnetic strip, the system will automatically emit a "ding-dong" sound.

This is especially suitable for families with children, allowing for quick detection of children opening the refrigerator without permission.
