Description

This wireless door and window sensor alerts you when a freezer, refrigerator, or any door stays open too long. The 60-second delay prevents false alarms while you're actively using the appliance, then triggers a 90-decibel chime loud enough to get your attention without being jarring. The ultra-slim design (0.32" thick) fits discreetly on most fridges and freezers without taking up space. Installation takes seconds—just peel and stick the magnetic sensor and alarm unit to your door, no tools or wiring required. The two components align magnetically, so they're simple to position correctly. Run time extends up to 2 years on batteries, with a low-battery indicator that flashes when it's time to replace them. Use it on kitchen appliances to prevent food waste and unnecessary energy costs, or on doors and windows as a basic security monitor.
