Contactless face recognition access control system

In the epidemic environment, people don't want to touch things outside, so we create a face recognition access control system that does not require contact. When it is detected that a person is approaching the door, the face recognition device is awakened to save power consumption. When the face recognition passes, the door is controlled to open. The work mainly consists of two parts: the door control part and the face recognition part. The two parts communicate through Bluetooth BLE. The door control part serves as the BLE server, and the face recognition part serves as the BLE client. The functions that the work needs to implement mainly include: face recognition, Bluetooth BLE communication (including server and client), servo control, door sensor switch driver, and proximity sensor driver. The development boards used include "Maix
BiT Kit", "BG22 - THUNDERBOARD" and "Arduino Nano 33 IOT". Among them, "Maix BiT
Kit" and "BG22 - THUNDERBOARD" are combined as the face recognition part and BLE client, and "Arduino Nano 33
IOT" is used as the door control part and BLE server. Communicate directly with the author: http://en.eeworld.com/bbs/thread-1222130-1-1.html
