| Overview
The 75F wireless Door & Window Sensor is a magnetic sensor that features an ultra-low power chipset from the nRF52 series and BLE 5.0 technology.
It consists of two parts: the sensor body and the magnetic part, equipped with double-sided adhesive for easy installation on doors, windows, and roll-up blinds to detect opening and closing.
Designed for remote monitoring of door/window activities, the sensor automatically sends notifications to a node or stat when the door is opened, allowing users to check door opening records on either the Hardware UI or portals.
