How did the door magnet find you?

Because after installing the door magnet, you can sense someone entering or leaving the door.

When residents with intelligent door magnetism come in and out, the intelligent door magnetism alarm will give an alarm after sensing the information of people's passing. Community workers can receive alarm information through mobile App, computer client, WeChat official account, telephone and SMS, and keep abreast of the entry and exit of people who need to be isolated at home.

Door magnetic principle

The door magnet consists of a wireless transmitting module and a magnetic block. There is a "reed tube" component at the two arrows of the wireless launch module. When the distance between the magnet and the reed tube is kept at 65438±0.5cm, the reed tube is disconnected. Once the distance between the magnet and the reed tube exceeds 1.5cm, the reed tube will close, resulting in a short circuit. When the alarm indicator is on, it will give an alarm to the host.
