Where is the weighing function of iphone?
The method of weighing items has sprung up on Weibo and moments, as long as you put the item on the iPhone, so how to weigh the iPhone? Here is a way for you to take a look at the weighing function of the iPhone.
How to weigh the iPhone?
Tips: first of all, confirm that your phone has 3dtouch function, and the online weighing is based on the extension of 3dtouch.
The first step is to open it using Apple’s own browser.
The second step is to place something capacitive (electrically conductive), such as an apple. Don’t put anything that scratches the screen.
The third step, you can see a weight on the screen, this is the approximate weight of the item, you can go to the electronic scale to compare.
IPhone weighing principle:
I want to study the level of detail of the new 3D Touch features on iPhone 6s. Is the heart rate monitor sensitive enough? Can I use it as a scale? So I assembled an application to show the touch force and found a scale.
In the absence of any better equipment, I gradually increased the touch pressure while shooting videos about scales and phones. The results are as follows:
Considering that there is enough error in my measurement, there seems to be at least a linear relationship between force and weight. The 3D touch pressure is given by a floating point in the range of [0Pol 6.66666]. This corresponds to the weight [0g337 g]. Each unit of pressure seems to correspond to about 50 grams.
Taking into account the difference between the final touch pressure and current of each change, I found that the minimum particle size was 0.020833, which, according to my previous measurements, was about 1 gram.
Update: 0.0208333 for lightweight 3D touch sensitivity. The following are the values for other sensitivity settings determined in the same way:
With proper calibration, it should be possible to use your iPhone as a gram scale. A warning: the object to be weighed must be detected through a capacitive touch screen.
The screen is obviously not sensitive enough to detect my pulse.
Therefore, a fairly accurate ratio is obtained by simply dividing the 3D touch force measurement by 0.0208333. Unfortunately, objects need to be capacitive to trigger the touchscreen. Since I didn’t want to scratch the screen, I chose strawberries for my first test (which can also be used as a pinch pen).
Note: the strawberries in both pictures are the same. My actual scale reading is 25.2g, while my 3D Touch scale reading is 220g-a good estimate. To do the same thing for an apple of 216 grams, my measurements are between 206 grams and 218 grams, depending on the direction of the apple.
I found that force values can also be accessed in Safari. You can use touchmove,touchstart and touchend events. For example: event.touches [0] .force. This value is a percentage of the maximum strength contact value; you can multiply it by the maximum value of 6.6667 to get a result similar to UITouch
Which brand of online automatic weighing machine is better?
There are many brands of online automatic weighing machine, so you should be careful when choosing, and try to choose a brand with a good reputation.
For customers, the selection of weighing machine is very difficult, the key reason is the setting problem. The weighing machine is actually a machine that converts the quality signal into the data signal output of electronic devices that can be accurately measured. Then, the geographical environment of the actual installation of the net weight machine is considered first. It is related to all the normal operation and safety performance and service life of the sensor, and even to the credibility and safety performance of all scales.
Why the setting of the weighing machine geographical environment occupies a very large factor, can be considered from the following many aspects. The key research topics are the melting of coating materials, the welding interface and the structural transformation of stress field in polyurethane elastomers in high temperature geographical environment. For weighing machines operating in high temperature natural environment, high temperature sensors are generally used. Under special circumstances, be sure to add thermal insulation, water-cooled radiator, air cooling and other industrial equipment.

The second is the damage caused by the heavy dust and moisture in the body to the common faults caused by the short-circuit failure of the sensor. Under this kind of geographical environment specification, the weighing machine with high tightness is used. Different weighing machines have different ways of sealing, and their tightness is very different. General seals with or with rubber gasket sealed argon arc welder and other electron beam welding machines and mechanical pumps filled with nitrogen. From the expected effect of tightness, the tightness of arc welding is good, and the difference between filling and sealing. Cleaning the sensor in the dry office environment can select the gasket sensor. Select diaphragm heat seal or diaphragm arc welding tightness for sensors in wet and dusty office environment.

What is the accuracy of automatic weighing machine (on-line weighing machine)
The accuracy of automatic weighing machine (on-line weighing machine) refers to the value that can be displayed on the weighing equipment display, such as 35.1, the accuracy is 0.1; the display is 35.01, the accuracy is 0.01. The automatic weighing machine is mainly composed of electronic components and weighing frame, which is used to detect whether the weight of the tested products in the product production line meets the requirements or to classify the tested products according to the weight grade. However, although the accuracy of automatic weighing machine is very high, there will be errors in a certain range if it is not operated improperly. The factors that affect the accuracy of automatic weighing machine are as follows:
1. Temperature, generally high temperature, low temperature, humidity and stability will also affect the accuracy of the automatic weighing machine. In general, the suitable working environment for automatic weighing machine is-5-40 degrees Celsius, relative humidity: 0.95 (no condensation).
2. Ground vibration, due to the loud noise in the workshop, frequent operation of the machine leads to ground vibration, and even the uneven ground in some workshops will affect the accuracy of the automatic weighing machine.
3. Air flow, such as fans, air conditioners and wind blowers in the workshop, will affect the accuracy of the automatic weighing machine.
4, static induction, charged objects or dust close to metal objects will produce static electricity, of course, it will also cause interference or even damage to the sensitive automatic weighing machine, so prepare anti-static measures in advance.
5, the product has the omission phenomenon, for example, the packing box seal is not tight enough to cause the omission, this phenomenon will also have a certain impact on the accuracy. For more information on the price of weighing machines, please click on the online customer service consultation.
6. The tested product is corrosive, and only a corrosive automatic weighing machine can be customized. In the early stage, through detailed communication with the engineer, what kind of material and what kind of technology are used for special treatment.
7. Human error, improper use in the production process has a great impact on the accuracy of the automatic weighing machine, and even damage the automatic weighing machine, the weighing sensor is easy to damage.
