PM2.5 detector simple trial

His own air purifier used for about 3 years, the brand Sharp, if according to the instructions on the note is HEPA filter can be used for ten years does not change, although not in the imperial city, international village, Chengdu and other major cities, but the original city also fog It is well-known that the replacement period of the ten-year filter is only applicable in Japan. But a look at Sharp's filter prices, a set down to more than 700+, true and false is difficult to distinguish, you can buy a millet, and change the filter every year is not heartache.

In line with the purpose of saving, I would like to buy a PM2.5 detector to see if Sharp's filter is still able to eat rice, so I started to focus on the detector:

First, air comprehensive detector

Green formaldehyde formaldehyde detection equipment haze PM2.5 electromagnetic radiation air quality home measurement formaldehyde benzene measurement self-monitoring test box portable six in one Deluxe Edition 688 yuan Jingdong direct link

This kind of multi-functional detector can monitor PM2.5, formaldehyde, TVOC, air index and temperature and humidity. There are many detectors with similar functions. The price is relatively high, but PM2.5 and formaldehyde detectors are purchased separately. Estimated to reach this price, it depends on the buyer's own demand for the function.

Second, Mi Jia PM2.5 detector price 399 yuan

Millet's economic benefits, personally feel that his products cost-effective, although performance is not outstanding, but can use 50% of the price to buy 80% of the performance of the product, but also enough. Advantages: With a battery, it can last for 2-3 hours. If you have a millet purifier, you can also interact with it. But it is said that the millet purifier's PM2.5 value has been optimized.

The two-hundred-thousand-hands-wandering journey of shopping to fully satisfy the second article: Mi-home PM2.5 detector first experience double 11 day stroll around and found that millet out of a PM2.5 detector, the price is not expensive, the key Is in stock, decisively handcuffed, millet official website links are as follows: Mi Jia PM2.5 detector - Xiaomi Mall Mi Jia PM2.5 detector - Xiaomi Mall Mi Jia PM2.5 detector is equipped with a compact black OLED screen size , And the height of the laser sensor...yyzn| Likes24 Comments62 Collections37View details


Third, DIY detector

The advantage of shopping for more worthwhile shopping is that you can listen to more opinions and take only the director's advice. Some people recommend the sensors of climbing vines, so they stroll in the richest home, and indeed there are DIY detectors.

The appearance of a very geek, using the sensor of climbing vines, I believe it is better than others.

Function introduction: Only purchased the formaldehyde detection function, feels the surgery profession to have the specialization, if brings the formaldehyde to test, the value friend has the detector which recommends the British Dart sensor, after others saw, the style is also the DIY style. PM2.5 detector is turned on, no power switch, no battery, rely on Android data line power supply, you can use mobile phone charger, charging treasure, computer USB, voltage requirements are not high, shut down when the power is off.

Let's take a picture indoors

Outdoor

The two figures show that the air quality inside and outside the room is the same. Even if you close the window, air pollution still exists.

The number on the mobile phone is even better, but I don't know where the pollution index 99 comes from.

The purifier was turned on. At the tuyere inspection, the data immediately fell below 40, indicating that the purifier still worked. However, strictly speaking, the inspection data at the tuyere was not prepared, but at least the wind blown out was still purified.


Summary: Although it is just a simple purchase of a detector and then made a statement, it may not be of much help. Actually, it is my first time to create an original cognition. It is not difficult to write originals, and I encourage you to write more. Share experience. My current habit is to buy something. First, what is worth buying and searching for everyone's experience, learning the knowledge, and looking at the lowest prices in history are really useful, and the quality of life and appreciation have been greatly improved.

Back to the detector itself, individuals understand:

1, do not care too much about the level of the value, many people Tucao millet purifier value is not accurate, but really show the value out of only his family. The accuracy of the data is only minor, and it is not a problem. It is nothing more than the general situation of the air under the reaction. Besides, the air is everywhere and the polluted air is pervasive. The so-called use of purifiers and masks is only passive. There is no better defense than nothing, and you do not care about the effect. Breathing is always in progress.

2. I used the detector for a while, and I collected it. I checked it on the line. I didn't think it was meaning to turn on my computer. I watched the change of value every day and I was still in a hurry, but it affected my mood, less pollution, and started from myself. ;

3, inside the detector as if there is a fan, has been starting to have low-frequency noise, like the current sound, is not suitable for long-term boot.

CAT6 Flat Ethernet Cable

Our Cat6 Flat Ethernet Cable provides high performance, as it uses 250Mhz to transfer data up to 1Gbps, faster than CAT5E. Allowing for greater bandwidth and, therefore, home and office productivity.
Cat 6 Flat Ethernet Patch Cables are designed for high density environments where clearance and space is limited.
CAT6 Ethernet Cable is manufactured in our own factory with 4-pair oxygen-free pure copper and RJ45 connector plugs with FU gold-plated contacts with molded strain relief snagless boot. Our high-speed Category 6 Ethernet cable has an in-wall PVC jacket.

Super five line identification is "CAT5E", bandwidth 100M, is the mainstream product;The identification of the six lines is "CAT6", with a bandwidth of 250M, used to set up gigabit network, which is the trend of future development.

The "UTP" method refers to the UTP -- Unshielded Twisted Pair cable, which consists of several pairs of Twisted Pair and one plastic sheath.

CAT5E of twisted pair also use 4 winding pairs and 1 anti-tension wire, the color of the pair is exactly the same as the CAT6 of twisted pair, namely white orange, orange, white green, green, white blue, blue, white brown and brown respectively.

Although the CAT5E of unshielded twisted pairs can provide up to 1000Mb/s of transmission bandwidth, they often need to be supported by expensive special equipment.Therefore, it is usually only used for 100Mb/s fast Ethernet to connect desktop switches to computers.If you are not prepared to upgrade your network to gigabit Ethernet in the future, then you might as well use CAT5E of unshielded twisted pair in horizontal wiring.

CAT6 of unshielded twisted pair: all parameters of the six classes of unshielded twisted pair have been greatly improved and the bandwidth has been extended to 250MHz.The CAT6 of twisted pair are different from the CAT5 or CAT5E types of twisted pair in shape and structure, which not only increases the insulated cross skeleton, but also places the four pairs of twisted pair wires in the four grooves of the cross skeleton, and the diameter of the cable is also thicker.
In addition to the traditional voice system still use three types of twisted pair, network cabling is basically using CAT5E or CAT6 of unshielded twisted pair Ethernet cable.
