The module can be easily manipulated to erase and add faces with physical buttons. Please make sure you don't expose them. DON'T USE THIS PROJECT TO CONTROL SECURITY MEASURES AS LOCKS etc.

It utilizes the TX510 kit module that contains a 3d Camera, a display and a flash. This All-In-One kit can autonomously, register and then recognise faces. It communicates via Serial to an ESP and via ESPHome can be controllable from Home Assistant.

Some ESP32 boards can't power the TX510 when in Identification process so if you have strange behaviours make sure TX510 gets it's 5v or else try with another board
