Question

two techniques to compensate the effect of distance between the sensor and forehead on the accuracy of IR temperature sensor!

Answer 1

Answer :-

Infrared temperature sensor is very usefull device.

Now a days it is much use in IR thermometer which use for measure a temperature without contact the body or object. So, the chances of infection and transferable diseases automatically get reduce. There are sevaral techniques to improve an accuracy of device.

As we know that Every infrared thermometer has a "distance-to-spot" (D:S) ratio it means the diameter of the area being measured compared to distance from the target.

Which can be improve by using adjustable focus lens with laser pointers that show the approximate center of the measurement area in IR thermometer for accurate readings.

Method to determine temperature would be to detect the difference between a normal temperature and a fever temperature as the distance is increased which gives faulty result.

As we know that only the emitted energy can indicate the object's temperature so we have to improve response time for IR temperature sencor.

Distance between sencor and forehead is adjustable to get quick response, it provides emissivity correction,for highest accuracy, it is best to allow some time.

infrared temperature sensor offer a great combination of speed, convenience, and accuracy,but only when they are used correctly.

Thus, we can compensate the effect of distance between the sensor and forehead on the accuracy of IR temperature sensor.
