If you're building up your smart home setup, introducing door sensors can be great for security, but they can bring a lot ...

In contrast, the hBN sensor developed by the team in Cambridge does not share these limitations and instead presents a multi-axis sensor of magnetic field with large dynamic range.

Magnetoresistance ratio enhancement opens door to highly sensitive magnetic field sensors. ScienceDaily . Retrieved June 2, 2025 from www.sciencedaily.com / releases / 2018 / 12 / 181220104648.htm ...

As you can see in the schematic above, this automatic air curtain door sensor switch design uses a common magnetic door switch for automatic on/off of the air curtain. The magnetic door switch ...

You see these a lot in, for example, door alarm sensors. Then again, there’s no real finesse to a reed. It changes state when it sees enough of a magnetic field and that’s about all.

“This sensor could open the door to studying magnetic phenomena in new material systems, or with higher spatial resolution than done before. The 2D nature of the host material also opens ...

Nest’s home security system costs $499 and comes with magnetic door sensors. Nest Secure is a modular system for arming your doors and windows.

The Door and Window Sensor P2 comes with an adhesive mount “that will not damage the wall if removed,” says Aqara, and a thin magnetic plate for additional mounting options.

Now, thanks to the work of [Jonathan Armstrong] we have such a firmware for the 433 MHz magnetic door and window sensors that you can pick up on AliExpress for $4 USD a piece.

"This sensor could open the door to studying magnetic phenomena in new material systems, or with higher spatial resolution than done before," said Prof Hannah Stern, who co-led the research with ...
