Use of Smartphones as Thermometer

South Korea/ Web Desk:

Many experts believe that the smartphone can be used for useful purposes after the hardware changes. Now the news is circulating that experts from South Korea have successfully experimented with the use of smartphones as thermometers.

The Korean institute of science and technology has developed a government-funded, cost-efficient, and effective thermal imaging sensor that works perfectly up to 100 degrees Celsius. The thermometer can also be added to the phone by attaching it to the smartphone camera.

Temperature sensing sensors are becoming more common in the context of the epidemic. They are commonly used in hospitals, banks, and other institutions.

In this context, many smartphones manufacturers want to add the most accurate thermometer to their phones.

An optoelectronics specialist at the Korean Institute of Science and Technology, Professor Jun Wen Choi, has developed a trustable, low-cost optical sensor that is free from other defects of the past. This sensor does not require any additional systems to cool down. This minor sensor can be easily mounted in a smartphone’s camera.

Sensor made of Vanadium dioxide absorbs Infrared radiations and converts it into electric signals, which in turn reflects heat in numbers. It is so sensitive that it converts heat into an electrical signal three times more accurately than a normal sensor.

Even if the temperature is 100 degrees Celsius, it shows its readings in just three milliseconds. Due to its high speed, it can also be used in automobiles.
