Abstract: The Coronavirus COVID-19 pandemic is the defining global health crisis of our time and the greatest challenge we have faced since World War two. Scientists first identified a human Coronavirus 1965. It caused common cold. Later that decade, researchers found a group of similar human and animal viruses and name them after the their crown like appearance. Seven coronaviruses can infect humans. The one that causes SARS emerged in southern China in 2002 and quickly spread to 28 other countries. More than 8000 people were infected by July 2003 and 774 died. Signs and symptoms include respiratory symptoms and include fever, cough and shortness of breath. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome and sometimes death. To prevent the spread of Covid -19 various measures have been taken. In our project we use automatic hand sanitizer with Ultrasonic sensor that uses ultrasonic sound waves to detect the object which saves time and produces better results. It can reduce the risk of spreading infections between coworkers. This allows for minimal contact with other surfaces and has stronger bacteria killing agent than average hand soap. The temperature is detected using Ultrasonic sensor HC-SR04 and Infrared thermometer MLX90614. This contactless temperature detector does not need to be operated by a human hence reducing the chance of getting infected. A pulse oximeter is a painless and reliable way for clinicians to measure a person's blood oxygen levels, this is done by using MAX30100.
