I am very happy to answer your question
1. There is a software called body temperature check, which can be found in the Huawei market. I feel it is not very accurate. Every measurement is different. , does anyone have a fever? Try it if it's hot and see if it's accurate. This seems to be a foreign software. One more thing, this software has a lot of advertisements.
2. Huawei mobile phones themselves do not support the functions of measuring blood pressure, indoor temperature, body temperature, and heartbeat. This may be because the body temperature detector requires many parts and is too thick to be installed on a mobile phone. , but eventually technology will definitely be able to solve this problem.
3. During the national epidemic, temperature measurement is required when entering and exiting any community. If Huawei mobile phones can break through this function, it will be really cool, attract countless fans instantly, and solve most of the problems. Recently, Huawei's Hongmeng system and HMS have competed against Google's Android system and GMS. Huawei has announced a lot of hard-core things, which have won the hearts of the people. Everyone's expectations for Huawei have been higher. They still hope to achieve a success in this battle. The Jedi counterattack campaign is a perfect counterattack around the world.
Finally, I hope my answer can help you or give you more inspiration.
To do infrared temperature measurement on a mobile phone, hardware must be involved, which is an infrared temperature sensor
1. This is the probe of an ordinary infrared thermometer, which is about 1 cubic centimeter. It needs to be The idea is to miniaturize it to fit inside a mobile phone.
And equipped with corresponding signal processing chips and circuits. Of course, this can be integrated into the motherboard. However, according to the current modularization trend of mobile phones, it is better to make it separately and connect it to the motherboard with a cable, which is also convenient for follow-up. repair.
Second, another idea is to use peripheral temperature measurement accessories to connect the mobile phone wirelessly or wired to read data, so that body temperature can be measured without changing the current configuration of the mobile phone.
But this feels like taking off your pants and farting. There is a ready-made infrared thermometer, so why do you need accessories? Why do you need to turn on your phone to check your temperature when you can check it directly? It's unnecessary.
The space inside the mobile phone is very precious, so an infrared probe is forced into it. Personally I think it’s really unnecessary!
1. An APP without hardware participation is just a rogue
To really measure accurately, hardware needs to be involved, that is, professional hardware emits infrared rays to detect body temperature, and then passes The mobile APP will feedback the detection results.
If the mobile phone itself does not have these things, creating such an APP can be said to be a scam. It is simply fake and has no meaning.
2. If you add hardware, it is not necessary, but it will increase the cost.
To be honest, in fact, under the current situation, it seems that there is such a need. In normal times, this kind of demand is completely and completely a fake demand, and no one will use this function at all.
On the contrary, if mobile phone manufacturers want to add this function, not only will the cost increase, but other R&D and design costs will also increase. Therefore, from a practical point of view, except in special periods, such a function is completely unavailable. If necessary, no manufacturer would do this.
3. There are professional equipment, such as forehead thermometer guns, which are also cheap
In addition, if you really have this need, just buy a forehead thermometer gun. This kind of equipment is more professional.
In fact, from the perspective of the market or users, professional equipment should be used to do professional things, instead of using a mobile phone to handle all functions. In the future, mobile phones will become airplanes, cars, and A fishing pole can be turned into a pen, a kitchen knife, and everything. This is unrealistic and impractical.
Mobile phone manufacturers are basically not very enthusiastic about this feature because it is not strictly needed and will increase the additional production cost of mobile phones.
To talk about this issue, we must first look at the principle. Although there are some apps that claim to be able to measure body temperature, they are not accurate compared to traditional thermometers. The principle of measuring body temperature on these APP mobile phones is probably through the thermistor sensor (NTC), and the resistance changes with the temperature change. Without increasing other costs, it is obviously unscientific to use the thermistor sensor inside the mobile phone to implement a thermometer. Because the NTC inside a mobile phone usually only measures the chip temperature and battery temperature, it will become very inaccurate when the machine heats up after being used for a long time.
If you want to realize a real thermometer, then the mobile phone must have a separate built-in sensor (thermal sensor). The result of this is that the cost of the mobile phone will increase. This function is not strictly needed by every user.
The current common practice among some mobile phone manufacturers is to develop mobile APPs only to monitor body temperature data. For example, the Xiaomi smart thermometer does not have a measurement function itself, but serves as supporting management software. So most of these APPs are only used for storage and data analysis.
There is no problem in developing this function, but the accuracy may be terrible.
There are basically two types of infrared emission units in mobile phones, the distance sensor and the grating emitter for facial recognition. Let’s not talk about the second one for facial recognition. If there is no camera to cooperate, the light will diverge and it will be difficult to capture some kind of stable infrared signal.
As for the distance sensor, neither the transmitting end nor the receiving end has been adjusted for accuracy. It is basically stable within a certain level, but it is not too much to insist that the light intensity emitted every time is the same. As a measurement benchmark, it is naturally impossible to obtain accurate results, and there is also a lack of shielding from ambient light, causing serious interference.
In summary, the results of the temperature measurement app produced with the current hardware configuration of the mobile phone are completely untrustworthy. Just play with it, there is no need to take it seriously.
As hardware technology and software programming become more sophisticated, mobile applications as self-diagnostic tools have grown significantly over the past year. The latest product comes from Fraden Corporation, which recently announced that it has received a U.S. patent for "Wireless communications device with integrated electromagnetic radiation sensor" for its new infrared thermometer technology with a built-in module for smartphones.
Basically, the technology they developed is a new infrared sensor built into smartphones that allows users to measure the temperature of a person or object without making any physical contact. Fraden Corporation develops temperature sensor technology for smartphones.
Fraden's smartphone sensor works with your phone's digital camera and takes less than a second to record a reading.
The Fraden sensor requires users to point at a person or object's face to record temperature readings. More specifically, the technology focuses on the use of non-contact infrared sensors that detect infrared signals naturally emitted from all surfaces. Users simply point the phone at the patient or object's face and it instantly records the internal temperature.
Putting the sensor into today's smartphones does not require any substantial changes to the phone itself: the entire infrared thermometer is packaged in a small ceramic SMD module that operates between 5 and 15 IR optics, IR sensors, signal conditioners, ADCs and I2C serial output circuits in the ?m spectral range.
It should be noted that the sensor can also be packaged into TO-46 standard cans with through-hole terminals. Further customization can lower the camera height to 4mm. Cost depends on quantity, with total incremental cost of components ranging from $1.65 to $2.50.
Fraden sensors are very small and do not require the manufacturer to make any major changes to the design. There are no protruding parts for manufacturers to consider. The sensor is located near the camera lens, so during temperature measurements the camera can help locate the object from which the infrared signal is detected and measured. Otherwise, phones containing this technology will look identical to their sensorless counterparts.
The infrared thermal imaging camera has two working modes: medical temperature and inanimate temperature. The former takes a snapshot measurement, while the latter continuously measures and displays the temperature.
To measure human body temperature, the infrared lens should be positioned 0.5 to 6 inches from the skin. Medical temperature range is 93 to 108°F (ISO required clinical accuracy is ±0.3°F).
To measure inanimate objects, the lens can be placed anywhere from 0.5 inches to the desired distance (all that is really needed is the surface area of ??the target object from which the IR radiation is collected), the camera's The angle of view of the lens is approximately 15°.
This sensor detects temperatures ranging from -22°F to +400°F, so it can be used in any environment (cooking, refrigeration), in the bathroom (bath water, shower temperature), in school (science experiments) , industrial sectors (automotive, chemical processing, construction), etc.
Fraden sensors are available for several different types of readings. However, the obvious target audience is parents with young children, nurses, doctors, veterinarians, inspectors or others who may have difficulty recording the temperature of a person, animal or object.
"Most smartphone models differ little from each other, with only minor changes," said Fraden Corporation president, co-inventor of technology and non-contact temperature measurement expert with more than 50 patents explains Dr. Jacob Fraden and inventor of the popular Thermoscan ear thermometer. "Vendors with breakthrough capabilities that can be used in real-life everyday situations, such as reading a child's temperature, can distance themselves from competitors. We believe this new patent can become an important competitive advantage for smartphone manufacturers."
As of now, Fraden’s sensors have reached ISO standards and are preparing to launch the technology immediately. In fact, the company has provided the sensor to qualified companies with important businesses in the mobile phone market, so I think Huawei can try to cooperate with this company and make a few changes in the camera without causing any loss in camera performance. , and it can achieve infrared temperature detection effect, which is something worth trying.
This can be achieved on a mobile phone, but the premise is that the mobile phone has an infrared scanner. If you do not have this function, then you will not be able to detect it if you have this APP< /p>
So the hardware must keep up with it
If the new mobile phone is equipped with this function, it will be a new selling point
A mobile phone is required Hardware support
However, the topic came up with a heart rate measuring APP, Smart Health, you can download it and play with it
Nowadays, an infrared thermometer gun costs 400-500 yuan, and it is not expensive to carry it with you. Conveniently, Huawei’s R&D strength makes it possible for mobile phones to integrate body temperature scanning functions
Mobile phones are related to physical health and the body obtains information. The social system is released and life applications can be theoretically developed. Mobile phones are currently screen-based, and gradually mobile phones Shrink it into a chip, implant it into the human body, and collect service fees regularly. In the later stage, everyone can use it for free. We only pay for in-app services. In the later stage, the environment changes drastically and electronics fail, returning to the original.
