Thermometers have played an important role in the medical field as well as in other fields. However, the first thing that comes to your mind when you imagine any thermometer that, a sick individual holding a thermometer in his or her mouth. Thermometers help people measure their body temperature and indicate if one has normal body temperature. Whether he has a higher temperature like in case of fever or has low body temperature that is when an individual is hypothermic. Non contact thermometers were used in industry for many years. However, because of the pandemic, they have been widely used because other thermometers, such as oral, armpit, and ear thermometers, could not be used during the pandemic.
