## Long description

The Eufy T89000D4 Door/Window Sensor is a compact wireless sensor designed to monitor the state of doors and windows. When a protected opening is ajar by approximately 1.5 inches (about 3.8 cm), the sensor triggers an alert to your smartphone and can activate a siren on the required eufy Security HomeBase. The sensor is powered by a CR-123A battery and comes in an unobtrusive white finish to blend with most interiors.

It integrates with the eufy Security ecosystem via HomeBase, delivers immediate smartphone notifications when an opening is detected, and provides an optional audible alarm on the HomeBase. Battery power (CR-123A) ensures long-lasting operation without the need for constant wiring.
