A new project from the manufacturer Seeed can turn the Raspberry Pi into a particularly elegant door lock. The lock is based on face recognition, for which the well-known Raspberry Pi Camera Module is used. The unlocking process is displayed on an IPS display with a resolution of 1980x1200 pixels.
The actual unlocking process takes place via a relay. This relay must be integrated into an existing door opener. The integration process is arguably the most difficult step of the project since Seeed provides detailed plans for setup at both a hardware and software level. The face recognition step is implemented by using a corresponding program created by coder Adam Geitgey.
If the unlocking process is successful, an SMS is sent to a stored number, but this requires an LTE-HAT to be installed. Users should always make sure that the Raspberry Pi is not accessible from the outside. This can be achieved by using a (securely) lockable box to store the board in.
