With the rise of intelligent hardware, major manufacturers have set foot in the intelligent hardware industry, so that the current intelligent hardware products are mixed, and more products are often labeled with smart gimmicks to increase their selling points, but actually there is no intelligence in the use process, so whether intelligence is still to be tested with actual use. Measuring the height of children may be a headache for many parents, because children are playful or naughty, and all kinds of non cooperation lead to parents' desire to simply understand the height change of children is difficult to achieve smoothly, but from its appearance, parents' desire will be easy to achieve, Yes, it is the product that Xiaobian is going to introduce to you today - Zhaike Intelligent Height Measuring Instrument.

▲ The packaging of the smart height measuring instrument for curtseys is not flattering. The white corrugated box looks a bit cheap. In this age of beauty, such a simple package is used to make the smart height measuring instrument for curtseys It feels a bit degraded. The top of the front is in Chinese and English“ Smart height measuring instrument for house guests ”The positioning of the product is very clear. The middle is the beautiful picture of the measuring instrument, and the bottom is the four major functions of the measuring instrument with the most selling points.

▲ Smart height measuring instrument for house guests On the top of the box is a two-dimension WeChat code for house guests, as well as three colors of this product, and on the bottom are three warm tips for protecting the package.

The strength of publicity information on the back is relatively weak, and the middle part is composed of the words "curtily guest network technology" and "curtily guest network technology" Logo and website, the lower left corner is the relevant parameters of the measuring instrument, and the lower right corner is the warm prompt given by the merchants to protect the environment. No wonder the merchants' packaging is so simple. In order to protect the environment, the merchants have given up the tall packaging, so I would like to praise the merchants here.

The most exciting moment finally came. Xiaobian opened the package with great expectation, and all the accessories were stacked in the plastic groove in a neat and consistent manner. Since the measuring instrument itself was made of plastic, there was no excessive protection inside.

Take out all the accessories in the package and stack them neatly as shown in the figure, in order: packaging box, measuring instrument host, measuring instrument base, instruction manual, certificate of conformity and three sections No. 7 battery.

At present, there are three colors of green, pink and light black available for Zhaike intelligent measuring instrument. The one received by Xiaobian is green. The host size of smart measuring instrument for house guests is 180 * 60 * 35mm. Although it is not very large, it is still a little large in the small knitting, which is not convenient to carry.

The fuselage and base shell of the smart measuring instrument of Zhaike adopt ABS plastic has excellent characteristics such as impact resistance, heat resistance, easy processing, good surface gloss, and the most important is safety, environmental protection, and non-toxic. Therefore, there is no need to worry about the safety of the smart measuring instrument for house guests.

The smart measuring instrument for house guests uses ultrasonic technology to measure height. By measuring the time difference between the sending and returning of ultrasonic, it can accurately measure height, and the accuracy can reach 3mm The equipment has no radiation during use.

The two bright eyes we see are the ultrasonic emission port of the smart measurement instrument for house guests. The aluminum ring and the black metal mesh make the acoustic port more like an eye. The fan formed by many round holes on the lower side is the speaker of the smart measurement instrument for house guests. The loudspeaker is loud and crisp in actual use.

The home guest intelligent measuring instrument is more concise in the key setting. There is a power on measurement button at the white green junction on the top of the host, and the entire device has only one button.

The main power supply of smart measuring instrument for house guest Three No. 7 batteries, facing the mainstream built-in rechargeable lithium batteries in the market, the choice of home buyers may not be very wise, but from the perspective of cost, it may be the best choice for businesses to choose battery power supply. Although battery power supply is not so environmentally friendly and energy-saving, it should also be balanced for cost. In order to ensure that the battery can be effectively connected with the electrode, the rear cover of the battery compartment is also made into a raised fixed fence to fix the battery position.

The corners of the smart measuring instrument for house guests have been treated with arc transition, and the surface is glossy and smooth, without any sense of separation. However, at the junction of green and white, the gap is a little too large, which affects the overall effect of the product.

There is a white icon of Zhaike Technology near the bottom of the base, and the top of the corresponding position is a level embedded in the base. The main function of the level is to play a horizontal reference role in the installation process. Ensure the installation level of the base so as not to affect the subsequent actual measurement effect.

The base is connected with the host through a groove socket connection, and the assembly and storage are quite simple and convenient. The corners of the base also adopt arc transition treatment, which ensures the overall effect and feel of the base.

The bottom surface of the base is the same as the bottom surface 3M paper stickers are used to paste on the wall. Before use, remove the protective paper on the surface and install it with reference to the spirit level. The installation is very convenient, but the disadvantage of using stickers is that it is not easy to replace. The bottom edges and corners are not treated with arc transition, so you should be very careful in the process of handling or you will scratch your fingers.

After fixing the base on the clean wall, we can measure the height. The maximum installation height of the smart measuring instrument is 200cm, the installation height is determined according to the actual situation, but it should be 3-50cm away from the top of the head. The graduation value of the measuring instrument is 0.5cm. After clicking to start the installation, when a "drop" sound is heard, the body should keep straight and look at the direction measuring instrument in front, and the final measurement results will be automatically announced by voice.

Due to the simple use of the smart measuring instrument, its operating instructions are also quite simple. The instructions cover the supporting APP downloads QR code, usage method of measuring instrument and product parameters.

In order to better and more simply record and analyze the changes in the height of children, the smart measuring instrument is also equipped with a special APP, Download the "Dwelling Growth" APP by scanning the QR code on the instructions. For the first time, you need to register the account as required, and set the parents' height so that the subsequent program can analyze the child's future growth trend. Since the APP does not support third-party account login, you must register an account to use it.

After the account registration is completed, you will enter the tutorial of using the pictures of the smart measuring instrument. After reading the tutorial, click Grow with Me to enter APP program main interface.

Growth of homesteaders The APP home page is also relatively simple. There are four navigation at the bottom, namely home page, briefing, growth circle and more. The home page mainly shows the latest height and weight measurement results. Since the APP needs to be equipped with a corresponding scale, we will not introduce weight here. Briefing is to show the height and weight change curve of children in the form of week or month. The growth circle is used to share the daily increase and weight change of children and to record the growth process of children every day. We won't go into details here.

The host can automatically synchronize data to the cloud through Bluetooth connection to APP. APP generates growth curves by collecting data in daily and monthly units, so that children's growth process can be mastered. Using the scale and measuring instrument together, we can measure the child's BIM, elevation, weight and other indicators, and give relevant growth suggestions according to the situation of other children of the same age in the database, so that each child can grow healthily.

 

According to the actual measurement data used by many people, such as the editor and daughter-in-law, the accuracy of the smart measuring instrument for house guests needs to be improved, and it is vulnerable to interference from the external environment. The maximum measurement error is about 30cm, and the minimum measurement error is about 0.5cm. Although the idea of the ultrasonic measurement of the homestead is very good, I personally feel that the technical maturity of this product has not met the requirements of the market, including measurement accuracy, intelligence, and APP practicability and usability. I hope that the subsequent improvement of the model will bring more surprises.

advantage:

1、 The host is easy to operate and fast to measure

2、 APP data synchronization is fast, and intelligent analysis is highly referential

3、 Ultrasonic height measurement is novel and radiation free

Disadvantages:

1、 Low measurement accuracy and limited measurement rise

2、 The APP has high requirements for the external environment. The APP has high requirements for the configuration of mobile phones. The models that can be perfectly matched are limited. At the same time, the APP cannot log in or has no bugs in this account after registration

3、 The degree of intelligence is low. You need to press the start key before measuring. Due to the limitation of installation height, it is not very convenient to use it. You cannot control the automatic measurement through APP

4、 The 3M sticker on the base is not easy to move after bonding, and the mobility is poor. It is recommended to use other fixation methods
