Introduction

Smartphones now have more and more features, but we may not all know, for example, the thermal imager function, this function is not all smartphones have, more exist on top of some of the more niche devices, so the thermal imager function to do on the phone, in the end, what are the problems? Here are the answers to some questions.

Can smartphones record temperature?

The answer is no:

Smartphones can be used as thermometers, but not very well, as described below:

The thermometer itself is very good to do. Because the general cell phone chip has ADC (digital-to-analog converter). But after making the thermometer, it is difficult to measure accurately. Because the phone itself heats, the test to the temperature is more or less always higher than the actual temperature. There are many people put the phone in the bag or pants pocket, it will be higher. Want to be the more accurate and fast test, the infrared temperature test is feasible.

Cautions:

1, because the temperature sensor inside the phone and next to the confidential components, the phone can not be used to measure the smartphone can not be used directly as a thermometer, because the phone itself heats, and the temperature tested to more or less always higher than the actual temperature.

2, smartphones can be connected through the Bluetooth communication function some Bluetooth intelligent temperature-sensing terminals achieve accurate, real-time monitoring of human body temperature, such as the market is currently selling some Bluetooth armband thermometers, Bluetooth intelligent temperature-sensing clothing, and other products to achieve 24-hour continuous monitoring of human body temperature function.

How to make my smartphone camera become an infrared thermal imaging camera?

Best smartphone thermal camera: smartphone thermal camera

It can convert thermal energy into a visible image on your phone. The MobIR 2 series is a new generation of smartphone thermal cameras from Guide Sensmart. Built with the world's first autofocus WLP infrared module, the resolution and performance are comparable to professional thermal imaging cameras. This product allows you to see what you can't see with the naked eye, and you can achieve real-time temperature measurement, night vision, photography, video, and other functions through the cell phone APP. It is an all-around partner for your daily work, family life, and adventure travel.

How far can a smartphone infrared camera detect?

-100-meter night vision - It helps you identify people and animals hundreds of meters away in the dark field

-Autofocus - Clearly no matter near or far

-Plug and play - Battery-free design, Easy to use

±2°C Conventional temperature measurement accuracy, comparable to professional testing tools.

Can a thermal imaging camera see walls?

No, you can't. The infrared thermal imaging principle is through the object's surface radiation infrared energy value, and then to the internal conversion of the specific corresponding temperature value and the corresponding color. Generally speaking, cannot penetrate detection. But if the wall surface there is long-term water or cracks caused by the decline in insulation performance can detect the thermal imaging camera, sweep a sweep can quickly observe out, very convenient.

What is the difference between infrared and thermal?

The most fundamental difference is, infrared temperature measurement is a non-contact temperature measurement, without contact with the temperature measurement target, while RTD, thermocouple, and thermistor is contact temperature measurement, must contact the target, resulting in other differences, due to infrared temperature measurement on the user's technical requirements are high, the absolute measurement accuracy is poor. Relative thermocouple accuracy is high.

What are the risks of thermal imaging thermometers?

There is no risk in the use of thermal imaging thermometers, and the use of such equipment does not cause any harm to the human body, so do not worry. It is in the actual application process, to more accurate body temperature monitoring, temperature measurement system in actual use, temperature measurement system because there is no reasonable temperature measurement area, by the environment such as air conditioning direct blowing, direct sunlight, mirror reflection, etc., may lead to temperature jump and report hot water cups, other heat-generating objects, poly heat objects, etc., may lead to respect, or in the delineated area detection, there are people holding cigarette butts in the background, the Alarm, the actual use, there are false alarms must pay attention to troubleshooting this type of problem.

Ordinary cameras and thermal imaging cameras which are better?

1.thermal imaging camera lens

An infrared camera lens is usually made of germanium glass. The glass has a high refractive index. It is transparent only to infrared light, and opaque to visible and ultraviolet light, so it can be divided into plants and animals in a very dark environment. The infrared thermal camera lens was compared with a common germanium lens used in ordinary camera lenses. The reserves are not low, but the extraction of high concentrations of germanium is very difficult, so the production costs of germanium lenses are relatively high, and the market price is often higher than ordinary camera lenses.

2.camera lens

Ordinary camera lenses are usually made of optical glass, whose most specialized function is, of course, to make light refraction (often called magnifying objects). Usually, optical glass is synthetic. For ordinary cameras/camcorders for infrared underexposure, the main reason may be the sensor and lens. The attenuation of infrared light by ordinary lenses depends on the lens material, the coating, and the wavelength range of infrared light.

Conclusion

Compared with ordinary industrial-grade thermal imaging cameras, cell phones inherently have larger screens, more storage space, and higher performance, which makes the use of thermal imaging experience and convenience will have some advantages. Thermal imaging cameras in daily life in addition to measuring body temperature, daily cooking when measuring oil temperature, and home appliance maintenance when measuring short circuit points, to be able to visualize the temperature and hot spots, thermal imaging camera can help.
