Another cool little sensor is this ‘door magnetic strip‘ we received today.
You can use this in a security system (that we will build together also) or for any kind of automation.
One tip when buying such a sensor is to be sure that it sends data when opening a door/window but also when it closes.
- Double sided tape
Some usage ideas:
- Home / Office security
- Turning heating/cooling systems off when a door or window is opened
- Mailbox notification
- Gate status
