                          Scheme parameters of infrared temperature gun frontal temperature gun


                          A. Technical parameters and product characteristics of the scheme


                          The best infrared wavelength of human body infrared thermometer is 9-13 μ m, and the maximum temperature measurement range is 35-45 ℃. Through the correction and calibration of the deviation between the surface temperature of ear and forehead and the actual body temperature, the accurate body temperature can be displayed.


                          The specific parameters of human body infrared thermometer are as follows:


                          Accurate measurement: measurement deviation ≤± 0.3 ℃.


                          Fast temperature measurement: the measurement time is less than 1 second.


                          Measurement distance: it can be adapted within 5-15cm without fixed measurement distance.


                          Screen display: LCD screen displays temperature measurement.


                          Unit conversion: use Celsius and Fahrenheit to convert each other.


                          Temperature alarm: set alarm temperature freely


                          Store data: store measurement data for analysis, reference and comparison

                          Non contact: measure the ear cavity and forehead of human body without touching human skin

                          Setting modification: it can modify and set parameters to adapt to white, black, yellow, brown people of different skin color, etc


                          Easy to use: multi key measurement, easy to operate


                          B. Calibration method of frontal temperature gun of infrared thermometer for human body


                          Ambient temperature: place the sensor in a 25.00 + / -0.02 degree water tank, press a key to confirm after it is stable, generally taking 30 seconds.


                          Blackbody temperature: first adjust the blackbody furnace to 37.00 + / -0.02 degrees, then plug the sensor into the blackbody furnace, and then press a key to confirm when it is stable. General time 20


                          C. Preparation of frontal temperature gun for infrared thermometer of human body


                          First of all, we need to have matching shell, LCD, sensor, and product specifications. In this way, the chip scheme can be developed in hardware and software

                          1. How many function keys are there in the shell


                          2. How many feet does the LCD need


                          3. Is the sensor digital or analog


                          4. Product specification: what kind of battery power supply, domestic or medical, whether calibration is needed


                          D. Product production test


                          Is there a blackbody furnace? The accuracy is 0.02-0.05 C. blackbody is required in the test phase


                          Constant temperature room in the factory? Adjustable for medium, high and low temperature


                          Do you know the radiator? There is a problem in the structure, optical components and sensors, which leads to the uncertainty of constant test and correction. Electronic design engineers may not be able to solve these problems


                          Do you have clinical experimental resources? (go to the hospital, they have people with fever, middle and small, who don't have fever, do some test data for a period of time.)
