Infectious diseases will significantly affect every aspect of our life, from work and education to healthcare and entertainment. In order to reduce its spread, safety guidelines both indoors and outdoors have to be followed. In this project, the focus is on scenarios related to indoor safety monitoring. Disease spreading is more severe indoors than outdoors. Particles from an infected person can move throughout an entire room or indoor space. The particles can also linger in the air after someone leaves the room. Preventing the person from entering if his temperature is high or if he does not wear a mask or if the crowd is huge in indoors is essential. This paper relies on intelligent technology: IoT devices, sensors, and computer vision. This paper uses these technologies to control the disease spreading in indoors.
