Automatic Door Unlocking System Using Facemask Detection and Thermal Screening

The pandemic of the coronavirus disease 2019 (COVID-19) negatively affected the lives and businesses of millions of people in 2022. Everyone is more afraid now, especially those who wish to continue their own activities while the world recovers from the epidemic and gets ready to go back to normal. Studies show that wearing a face mask significantly reduces the danger of spreading the virus and offers the user a sense of security. However, it is difficult to physically check to see whether this rule is being followed. The creation of a face mask detector that can identify face masks is the main objective of this research. Open CV and Tensor flow are used to identify face masks. Face mask recognition is included into both the Raspberry Pi and the USB camera. This encourages the use of face masks, helps catch safety violations, and maintains the workplace safe. MLX90614 is used to determine body temperature without making physical contact. The door is opened if the temperature is below the threshold, or 40 degrees Celsius, and someone is wearing a mask; otherwise, the door must be locked to stop the buzzer from going off.
