Contactless Temperature Detection Doorbell
Abstract
Several studies have looked into how long SARS-CoV-2 can persist on porous and non-porous surfaces. Viable viruses can be identified on non-porous surfaces for days to weeks. Since the beginning of the COVID-19 epidemic, there has been an upsurge in poisonings and injuries caused by the improper use of cleaners and disinfectants. Some disinfection methods, particularly those that include fogging or misting, are neither safe nor effective for inactivating the virus unless they are done appropriately. To cater to the needs of the pandemic, a lot of new technologies and innovations were introduced. Not only does identifying a person who has COVID pose a problem but also the challenge to stop the spread via surface contact became a major issue. The smart contactless temperature detection doorbell has been playing an important role in protecting our modern workspace since they were invented.
Our project aims to be a critical safety shield for the general people in the fight against the epidemic. An ultrasonic sensor is integrated with the automated doorbell system to ring the doorbell with a hand motion. A temperature sensor Mlx90614 is also included in the system, which records the temperature of the person standing in front of the door. If the person outside is there, the ultrasonic sensor detects it and buzzer sounds developed. The system helps in reducing physical contact, and the results obtained are at par with the already existing solutions and provide a few advantages over them.
