A thermal imaging system is always a superior gadget that bestows the user with the contentment of investigating a scene. Of course, thermal imaging cameras have a variety of uses like investigating fire accidents, hunting, and surveillance, find missing pets and kids, detect leaks in pipes, find out hot electric wires, etc.

But how does it work? That’s very simple.  Unlike an ordinary camera, thermal imagers use a different technique to capture the scenes in front of it.

All objects on earth emit infrared radiations in the form of heat and they vary from each object. This unique radiation from every object is termed as the heat signature of that object.

Thermal imagers have a thermal sensor that is capable of picking the heat radiated by each and every object in front of it.

The variations in the heat of the objects are captured by the sensor in the thermal imagers and sent to the electronic circuit inside to show the image on the screen.

Did you know? Thermal imagers are now being used to detect the body temperature of people at places like airports, shops, hospitals, and other areas as a preventive action for COVID-19. As the primary symptom of coronavirus is fever with elevated body temperature, these contactless thermal imagers can check if the person has elevated body temperature by pointing their forehead.

Unlike an ordinary camera, the thermal imaging camera produces images in a palate of colors like red, orange, yellow.etc.

There are also thermal imagers to display images in two or more color palates. But, these thermal imagers are big sized cameras that are extensively used by the army personnel, firefighters, etc and so normal people always don’t intend to carry such a heavy in the hand.

Instead, they need it somewhat compact and weightless. In order to satisfy their demand, common thermal imagers were manufactured in a very small size which is almost used as a smartphone accessory.

These handy devices can be simply connected to the android phones and from then your android phones can serve as a thermal imager. In this article, I have listed the best top-ranking thermal camera for smartphones which shall be greatly helpful to the readers.
