WiFi Door Magnetic Sensor Alarm: A 100dB Acousto-Optic Alert for Smart Home Security

This WiFi Door Magnetic Sensor Alarm offers a practical entry point into home security, designed to monitor doors and windows. It functions as a magnetic contact sensor, triggering a noticeable 100dB combined sound and light alarm when the protected point is opened. The device integrates into your existing smart home setup via a 2.4GHz WiFi connection, operating on the IEEE 802.11 B standard, and is powered by a straightforward DC3V supply. It is listed under the product category of a smart home control system, providing a basic yet functional layer of security awareness.

Features and Construction

The core function of this device is to sense the opening of a door or window using magnetic contacts and respond with an alert.

Material and Build

The product is constructed from the electronic components and housing necessary for a magnetic sensor alarm system. Its build is centred around reliably detecting the separation of its magnetic contacts and initiating the alarm sequence. The device is designed for the specific task of securing entry points, with all specifications focused on this security function.

Size and Practical Fit

As specific dimensions are not provided, the device is intended for discrete installation on standard door and window frames. Its primary design consideration is the reliable alignment of its magnetic sensor components to ensure the contact is broken when the protected entry point is opened. The product's form factor is tailored for its role as a magnetic sensor within a smart home ecosystem.

Uses and Placement

This sensor is versatile for various residential settings where monitoring entry points is desired.

Event or Professional Use

While primarily for home use, the loud 100dB alarm and WiFi connectivity make it suitable for securing temporary spaces, small offices, or storage areas where instant audible alerts are beneficial. The ability to integrate it into a network as part of a smart home control system allows for remote monitoring scenarios.

Everyday Home Use

For daily home security, the sensor provides a clear alert when a monitored door or window is opened, offering peace of mind. It is a practical choice for ground-floor windows, back doors, or any entry point where you want an immediate, localised alert. The low static current (≤120 µA) supports efficient battery life for routine use.

Benefits and Buying Value

The value of this product lies in its specific function and integration capabilities.

Reuse and Low Maintenance

The device is designed for ongoing use as part of a home's security posture. Its low-power operation (≤120 µA static current, ≤20mA alarm current) on a DC3V supply suggests a focus on energy efficiency for sustained operation. Maintenance primarily involves ensuring the power supply is maintained and the magnetic contacts remain correctly aligned.

Why Choose This Product

This WiFi Door Magnetic Sensor Alarm is a focused choice for adding a basic, audible and visible alert system to doors and windows. Its key differentiators are the specified 100dB acousto-optic alarm and its 2.4GHz WiFi connectivity for smart home integration. It provides a concrete security function with published electrical specifications, making it a defined component for your home monitoring setup.
