Common light levels outdoor
Friends often refer to Google as a "dog", but the "dog" has been registered by thunder first.
Let's call it back to Google, a poetic name.
Google, a good dog.
People who often engage in technology, please use this dog well, you will get twice the result with half the effort.
Today, I want to know what the light intensity is in various environments. I have tested the light intensit
absolute pressure is greater than atmospheric pressure, it is equal to the difference of absolute pressure minus atmosphere, namely: gauge pressure = absolute pressure-atmospheric pressure4. Negative pressure or vacuum degree (also known as air pressure): that is, the absolute pressure of the medium under test is lower than the atmospheric pressure. Vacuum degree = atmospheric pressure-absolute pressureTo a pressure unit conversion URL:http://yali.51240.com/1.4 Air quality sensorDue to the requ
results of the ADC can be left-aligned or right-aligned in a 16-bit data register. The analogue look- door dog feature allows the application to detect whether the input voltage exceeds a user-defined high/low threshold. The STM32 transforms the ADC into 2 channel groups: The Rule Channel Group and the Injection Channel group. The rule channel is equivalent to the program you are running, and the injection channel is equivalent to an interrupt. When your program executes normally, interrupts ca
to another professional course question. When I had a dog, I had to search for all the papers.English reading is the key point. There are three mistakes and four mistakes. If you make the five mistakes, I am sorry to tell you about your postgraduate entrance exam, how many points do you have to take? I think it's worth three hundred and five, right ?, Three hundred and five ?! It's a busy job.From four hundred, you should not be too high. This is just enough for review. You have to study the cu

There is also the positioning sdk currently used by Baidu map, and the returned data does not have altitude data. This is also one reason that Baidu gps is not used for positioning.
When the base station locates, it feels that Baidu returns faster and faster than AMAP data. The address resolution or search is the same. I don't know if Ba

When you want to view the indoor temperature, use a button to start the injection conversion group (3 Indoor probes) the indoor temperature is temporarily displayed. When you open this button, the sy

Work around the clock: speakers work around the clock, using outdoor waterproof aluminum shell, rainproof, dustproof, insect-proof, with a Tweeter speaker, ensure that the military song shine powerful.

Lead to death from lightning strikes.To find the truth. CCTV "is true" column group reporter, came to China Electric Academy high-voltage outdoor experimental field simulation lightning strikes experiment, according to the experimental plan.

V-band Microwave Product Application
According to the global V-band (60GHZ) microwave product deployment, the main advantage is that the band can be used free of charge, reducing the cost of spectrum consumption; in 256QAM modulation and demodulation mode can support 400Mbps above business throughput. In addition, because the oxygen attenuation in the V-band band is very large, the microwave transmission distance is very limited (maximum about 300m), so the frequency mul
, using simple modulation and coding mechanism, can reach the information rate more than 100mb/s in a short distance. UWB can make a tradeoff between the information rate and the coverage range.
A large number of applications are suitable for using UWB, including: High-speed wireless personal network (HDR-WPAN), Wireless Ethernet Interface Link (WEIL), smart antenna Area network (IWAN), outdoor Point-to-Point Network (OPPN), sensor, positioning and i
workmanship, poor quality, but cheap. System integrators often prefer to recommend similar products in order to reduce costs, and many schools are less likely to be defensive because of their lack of systemic performance. Seemingly a very small problem, resulting in the entire network cabling system external image damage.

Campus network wiring In addition to outdoor cable according to the standard to choose a special
more strong, network management staff at random to decorate the situation is also more common, because the network cable does not install lightning protection devices, outdoor network cable almost become a lightning fuse, Thus, lightning failure occurs frequently.
Small tip: Lightning Current in addition to through the communication cable or power cable, in addition to direct attacks on LAN devices, it is possible to indirectly damage the LAN system
If I design a mobile phone for myself, it is first a reliable communication tool, not the iphone, millet, Huawei, ZTE, Samsung and other toys. Second, not only to adapt to urban use, but also to adapt to outdoor hiking use.

Chao made the second big thing in Sina's history.
Sina's first big event is the merger of the four-sinanet, which is December 1, 1998, the birth of Sina, the Internet began to enter the territory of China's media industry.
10 years later, through the acquisition of the core outdoor advertising business, Sina out of the portal competition in the Red Sea, began to restructure the Chinese media industry map. Since then, no advertiser can ignore

First, the outer skin: Indoor optical cables are generally used polyethylene or flame-retardant polyethylene vinyl, the appearance should be smooth, bright, flexible, easy to peel. Poor quality of the optical cable skin finish is not good, easy and inside the tight sleeve, aramid adhesion.
Outdoor fiber optic cable PE sheath should use high-quality black polyethylene, into the cable after the skin smooth, bright, uniform thickness, no small bubbles.
