Implementation of Transfer Learning-based Mask Detector on Smart-Locked Door with Raspberry Pi

The status of covid 19 as a pandemic by WHO has not been revoked, not even downgraded into endemic. The masks and vaccinations are still consider as “the most effective weapons” against the virus. Using masks indoors is still mandatory. This paper designed a device that turns an ordinary door into a smart door that only gives access to people who wear masks. A camera and monitor is installed in front of the exisiting door and solenoid lock is added as additional keys. TensorFlow and OpenCV on Raspberry Pi are used to detect whether someone is wearing a mask or not. Based on the test results, the effective distance of the device is 2,7 m with 98,11% accuracy.
