Non Contact Thermometer
Non-contact temperature measurement solution

The traditional body temperature measurement is a contact measurement using a mercury thermometer, which has the advantages of stable performance and small error, but has the disadvantages of long measurement time, high risk of cross-contamination, and easy to cause mercury poisoning due to glass breakage.

Infrared ear thermometer is the most commonly used thermometer. It can test body temperature with a slight amount of forehead or ear, and it can also prevent body infection. Infrared ear thermometer collects infrared radiation from ear cavity and tympanic membrane through infrared sensor/ infrared photoresistor. And converted into a digital signal, the main control CPU unit converts the digital signal into a temperature value and displays it on the LCD screen. Compared with mercury thermometers, infrared ear thermometers have the advantages of high precision, high resolution, fast measurement speed, easy operation, safety and coSuZhou LongShowort.

Now the country is also banned from mercury production. I believe that the application of infrared ear thermometers will become more and more extensive in the future.
Why choose the infrared filter of SuZhou LongShow?
     Based on the control of cutting-edge technology in the industry, the R&D team of SuZhou LongShow combines the semiconductor process with the application of vacuum coating, which can be used to customize the various filters of the complex processes.
     The SuZhou LongShow filter can be adjusted according to the needs of supporting products, which can achieve the purpose of improving product performance.
     1. Broadband filter from 5.5um to 14um absorbs effectively integral area of the greater the response rate of the corresponding temperature range. Our company produces 5.5um-14um filter in 5.5 up to 14 after as before, but the part of the market 5.5 um -14um filter, may fall after 5.5um-7um, or 7.5um-8um after the fall and absorption area is seriously missing, affecting the corresponding temperature range detection rate.
     2. The best use of thermal power release is 7um-14um, or 7.4um-14um, and the human body temperature corresponds to the absorption peak is 10um, and 9um is the absorption peak of silicon chip. According to this application, our company has been modified to raise the temperature in 9um. 7um-14um or 7.4um-14um PIR near the temperature range, and the short temperature range can effectively isolate the acousto-optic electromagnetic noise, and the sensitivity is better.

What is the difference between infrared thermopile sensing temperature sensor and ordinary temperature sensor?
A: Infrared temperature sensor and temperature sensor are commonly used temperature measuring instruments, which can directly measure the temperature of objects.

Infrared temperature sensor
     A sensor that utilizes the physical properties of an infrared ray to measure. Infrared is also known as infrared light, and it has reflection, refraction, scattering, interference, absorption and other properties. Any substance, as long as it has a certain temperature (above absolute zero), can radiate infrared. Infrared temperature sensor is not direct in contact with the measured object, so there is no friction, and has high sensitivity, fast response and so on.

Temperature sensor
     General measurement accuracy is higher. In a certain temperature range, the thermometer can also measure the temperature distribution inside the object. But for the movement of small objects or small heat capacity will produce a large measurement error. The commonly used thermometer has bimetallic thermometer, glass liquid thermometer, pressure thermometer, resistance thermometer, thermistor and thermocouple and so on.

the unique features of infrared temperature sensor
infrared temperature sensor, also known as the non-contact temperature sensor, is mainly used to detect the thermal radiation of the object to emit infrared, so as to measure the temperature of the object, which can support telemetry.
The advantage is:
1, Due to the non-direct contact with the measured medium, there is no need to consider some of the physical properties of the contact medium.
For example: adhesion, corrosion, wear and so on do not cause damage to the sensor. And contact type will face the additional solution to these problems.
2, Limited space. For some remote sensing objects that are not easily accessible, the temperature can be measured at a distance.
3, for some objects that are inconvenient to be measured, the measurement can be achieved, such as rotating machinery, moving targets and so on.

Non-contact measurement temperature is deviated, for example, a cup of hot tea, with non-contact measurement, which measured when the, there is a certain distance, and this distance with air flow and there are complex gas doping. However, the probe is going through the air to reach the temperature of the measured object, so there are slight differences, but after the correction by measuring the error will be reduced.

4, the measuring speed is fast, theoretically, the temperature of the measured object can be measured in 0.1second.

What are the typical applications of infrared thermopile temperature sensors in intelligent hardware?
Intelligent switch
such as measuring the human body or constant temperature of the static or existence, people who need to detect the static or the existence of places, such as intelligent air conditioning open. intelligent air conditioning should be both energy-saving and human coSuZhou LongShowort. Infrared temperature sensor can meet the detection of human existence, and can detect the temperature of the human body, is the application of the ideal sensor selection.

Smart home
Quiet night, the existence of night light, can meet people's lighting needs of the weak lighting. The temperature sensor can determine the state of the human body, and in accordance with the state of the human body lights and turn off the lights in a timely manner.

Security
In an area where life may not approach or enter, the timely trigger alarms or actions to prevent human or animal from being harmed by various external forces.

The applications of energy saving
The existence of static sensors can sense accurately the existence of the human body at any time, open around the function of the human activities need, in the absence of the presence of the human body, automatically turn off the relevant action and intelligent energy.
