Amazon Fridggi Standalone Fridge Door Sensor with Delay When Left Open, 60sec, 120sec, 180sec Reminders

This device gives you progressive reminders if a refrigerator or freezer door is left open or ajar—from gentle beeps to an optional louder alert—so you can avoid food spoilage and wasted energy.

Key Features

• GENTLE ALARMS – Alert after 1 minute (for 2 seconds), a second alarm after 2 minutes (for 4 seconds) when the fridge door is still open or ajar.
• CONTINUOUS ALARM – Alert after 3 minutes (stay 60 seconds) will help you close the fridge or freezer door in normal situations.
• REPEATED SIREN – Loud Mode includes an additional 110dB Siren every 4 minutes (stay 20 seconds), activate using SET Button (4 beeps confirmation).
• FOUR MODES – Quiet (80dB), Medium (85dB), Normal (90dB with a beep every 10s), Loud (95dB, with a beep every 10s and a 110db Siren every 4 minutes).
• EASY TO USE – FRIDGGI emits a low volume beep when you exceed the allowed gap between the Alarm and the mini sensor; open/close the door to check before peeling the double-sided tape.
