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.

Package included:

  • Sensor
  • Magnet
  • 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
