Wireless Sensor Network Node Hardware Design Base on CC2431

Wireless Sensor Network, the self-organized network consists of lots of sensor nodes, which already applied in the monitoring areas, has potential application prospect in the sectors such as military, industrial control, city management, medical and health, environment monitoring, rescue relives and dangerous works, etc. "MIT technology commentary" lists WSN as the number one of the top 10 innovations of new trends. WSN also became the key study subject as it has already among the priority-developed industries in the national 2010 prospect plan and the 15th five-year plan.Sensor node design and implementation are the focus of the study of wireless sensor networks, In this paper, the existing wireless sensor network communication protocol and sensor node design based on the needs analysis is given based on the IEEE802.15.4 and ZigBee protocol, scalability Sensor nodes and the Sink node design, and the use of TI's CC2431 (integrated CC2420RF and 8051 CPU) to design the corresponding c..ircuit schematic and PCB.In addition, considering the wireless sensor network nodes' location of the sensitivity of the design of the software to fully utilization, the advantages of CC2431 is designed to achieve location-based positioning of the sensor nodes.After testing, the paper designes the sensor nodes that are in line with the electromagnetic compatibility and signal integrity requirements, RF part of the design specifications in line with the TI and the impedance matching circuit board design is right. Sensor nodes can be the correct data collection and transmission. Sink nodes can receive and send data to the target sensor nodes rightly or the target pc; In addition, Sink nodes as well as Sensor nodes have low-power, low-cost and small size and so on.

Telecommuting

Telecommuting– substituting the computer for the trip to the job —-has been hailed as a solution to all kinds of problems related to office work.

　　For workers it promises freedom from the office, less time wasted in traffic, and help with child-care conflicts.Do you need cheap ralph lauren polo shirts? For management, telecommuting helps keep high performers on board, minimizes tardiness and absenteeism by eliminating commutes, allows periods of solitude for high-concentration tasks, and provides scheduling flexibility.

In some areas, such as Southern California and Seattle, Washington, local governments are encouraging companies to start telecommuting programs in order to reduce rush-hour congestion and improve air quality.

　　But these benefits do not come easily.Oh，Jerry，don＇t let＇s ask for the moon.We have the ralph lauren polo shirts. Making a telecommuting program work requires careful planning and an understanding of the differences between telecommuting realities and popular images.

　　Many workers are seduced by rosy illusions of life as a telecommuter. A man＇s best friends are his Lacoste Polo Shirts.A computer programmer from New York City moves to the tranquil Adirondack Mountains and stays in contact with her office via computer. A manager comes in to his office three days a week and works at home the other two. An accountant stays home to care for her sick child; she hooks up her telephone modern connections and does office work between calls to the doctor.

　　These are powerful images, but they are a limited reflection of reality. Telecommuting workers soon learn that it is almost impossible to concentrate on work and care for a young child at the same time. Before a certain age, young children cannot recognize, much less respect, the necessary boundaries between work and family. Additional child support is necessary if the parent is to get any work done.

　　Management too must separate the myth from the reality. Although the media has paid a great deal of attention to telecommuting in most cases it is the employee’s situation, not the availability of technology that precipitates a telecommuting arrangement.

　　That is partly why, despite the widespread press coverage, the number of companies with work-at-home programs or policy guidelines remains small.

international

Comparing with regional economic integration, international eco-economic integration expands the scope of international cooperation from economic field to eco-economic field, and also develops the narrow meaning of welfare (economic welfare) which is pursued by regional economic integration to the generalized well-being. As a new way of international cooperation, international eco-economic integration has a variety of effects in promoting the overall development of the international region, such as the system effect, the basis effect and the effect for sustainable development. There are China, Japan and South Korea which are the most economically active Asian countries in the Pan-Yellow Sea Area. These are my cheap northface jackets!At present, the economic output of China-Japan-Korea is about one-fifth of global GDP. They gradually become the world’s third largest economic power and the new engine for driving world economic growth. Whether the Pan-Yellow Sea Area could achieve sustainable economic development or not, not only related to the interests of this region and countries in this region, but also related to long-term development of the world economy.Pan-Yellow Sea eco-economic integration is a kind of practice of international eco-economic integration.This is your favorit chi hair straightener! It is an eco-regional economic integration way for this region which stands for the transnational cooperation both in the ecological field and the economic filed. Specifically, based on the Pan-Yellow Sea large marine ecosystem, Pan-Yellow Sea eco-economic integration has China, Japan and South Korea as the main participants, and it also includes rich connotation, such as large marine ecosystem coordinated protection, promoting free trade and eco-environment coordinated development,?I think these ralph lauren polo shirts are the beginning of a beautiful friendship.construction of eco-logistics network and so on. Promoting Pan-Yellow Sea eco-economic integration is conducive to achieving regional economic sustainable development, the promotion of regional welfare, and also conducive to achieving mutually win-win benefits through the joint efforts of China, Japan and South Korea.However, Pan-Yellow Sea eco-economic integration involves several countries and multiple levels’cooperation.

Fashions and Me

Due to the abundance of the material goods and rapid development of civilization, people are becoming more and more particular about what they use and wear. An increasing number of manufacturers have focused on designing things that will appeal to consumers. Those who sell a lot of their products dominate the market and lead a trend that most people will follow right away. If their products do not improve, they are doomed to fade away. Why are so many people addicted to fashionable things? I think it's because they are fond of showing off . They want to dress themselves in amazing costumes and perform unique actions to draw others' attention. Actually, many people only buy certain trademarks without making sure that the product aren't fakes. This situation allows the market to be flooded with pirated copies. It can't do any good but increase piracy, cause unexpected losses to original companies and harms our international image. Those polo shirts are very good!Moreover, following some trends can be dangerous. Moreover, following some trends can be dangerous. Some gangsters would like to encourage others to take drugs, have tattoos, and do things that are illegal and immorals. They will call people who reject these things chickens or cowards. Because of this, some people try these bad things to show that they are brave. Oh，Jerry，don＇t let＇s ask for the moon.We have the ralph lauren polo shirts. This disturbs out tranquil society and make more and more young peoples, who are the future's leaders, descend into degeneration. this situation will go from bad to worse. It is really astonishing, isn't it? As for me, I also like to wear fabulous clothes to make myself look cool. But I am not a blind follower of all fashions. I decide which fashions to follow. A man＇s best friends are his Lacoste Polo Shirts.A fashion attracts me only if I think it's worthy of my attention, time and cash. Indeed, aside from fashion, there are other meaningful things for us to pursue, such as peace of mind and being kind to others. I often say to myself, “Self-control is the true nobility. Why just plunge yourself into the pursuit of fashions? Why just be obedient to others' ideas? Why not be your own master?” In my opinion, as teenagers, we should acquire knowledge and do something significant for our society, and not just be snobbish pursuers of fashions.

The Angel In My House

My sister was watching me sympathetically as I burst into tears for what annoyed me. Holding my hand firmly in hers, she sat by my side without uttering a word.
Willingly or not, I had been her sister for 13 years since I was 7 years old.Where can I get nike running shoes? Due to her arrival, I then childishly thought that I was thrown into a world of darkness, anger, frustration and self-pity. Once a lovely girl, I felt condemned by this fate to becoming a desolated burden ---- all the adults around complimented the newly-born, charming creature while neglecting my presence.
A cloud of jealousy hung over my once peaceful heart. I muddled through each day by sharing all I had previously had enjoyed alone. And all I had to cling to was to hit her and shout at her on our parents’ back.
My sister was so scared of me that each time when she was left alone with me, I could notice her trembling----and that pleased me even for years. How much do these cheap straighteners cost?But, I also knew that she respected me from the bottom of her heart----though I never admitted that until that day when I participated the College Entrance Examination. My parents as well as my sister all came to bolster morale for me outside the school gate. I was thoroughly prepared. I passed the line that separated the examinees and the supporters, and walked on nearly 100 meters, I suddenly heard my sister’s voice:
“Your pen-box! Sister, you forget your pen-box!”
Turning back, I saw my sister’s little body rushing past the security guards all the way towards me.
When she run up to me, what she heard was my sneer: “Pen-box are not allowed. I’ve picked out the pens.”
Then she answered breathlessly: “Oh!” daring not to look into my eyes.
Seeing my sister walk out with a disappointing back, I suddenly realized that she was always waiting for an opportunity to do something for me.
Later, when I went to university in Beijing, I tasted the ache of loneliness.You can pay for Lacoste Polo Shirts by credit card here. Furthermore, two shocks in quick succession allowed me to learn that my sister’s really means a great deal to me.
The first thing was that, as Mother told me, after my leaving, my sister insisted on not moving any of my things. She even put my towel besides hers. She said, whenever she entered the bathroom, that would remind her of my smiles, my jokes, my being a patient listener.
Then came the second shock: I could not remember when I gave her a smile, when I ever told her jokes. As for “a patient listener”, all that came to my mind was that my sister kept telling some trivial incidents in her school day, but I put none of them into my heart, only minding my own business. Yet as long as I felt sad, it was my sister who would sit by my side, watching over me.
This summer, my father rented a house by the Nanli Lake and took us all there for several weeks. This time, it was me who was expected to catch the opportunity to push our relationship further, and to let her know how I really felt.
The first morning, we went fishing. We stared silently at the tips of our rods, at the dragonflies that came and went. I lowered the tip of mine into water, tentatively, dislodging the dragonfly. I looked at my sister, who was silently imitating me, and yet there was even no dragonfly on her rod! Then I intentionally let her hold my rod, her eyes watching. For a while, I could experience her state of mind---she was pleasantly surprised by my behavior showing acceptance.
Being wild with joy, she finally caught two Yuenan fish, hauling them in briskly and put them in the net skillfully.
Then I had to accept that, as the time went by, my sister had grown up much more independent, being able to manage many things all by herself. But still she followed me step by step, imitated whatever I did, convinced everyone of her classmates that I was the best sister in the world. I knew that she tried her best to let me know that: she loved me.
Now I once again complained in her arms, asking for her comfort. Thinking of the past 13 years with a sister, tears of happiness poured down my cheeks. For I had always felt my sister’s presence, in both heart and life. I was lucky, so lucky, for my parents had given me a gift more precious than doting on me; a gift that helps me know what love is and how to treasure it. She is the angel in my house.

yourself

In the second place, thinking too poorly of polo shirts, you will find it difficult to cultivate your own faculty. If you never find that in fact you are more capable than you believe, it's impossible for you to cultivate your potential faculty. You will think you are having nothing special. It's reasonable that you don't have some achievements; it's reasonable that you follow others when doing ralph lauren polo shirts; and it's reasonable that you taste failure repeatedly. You are satisfied with what you are, and don't think of being successful one day. In fact, you are wasting your capacity unconsciously.In the third place, thinking of yourself properly, you will be rewarded all the time and feel hopeful every day. Thinking of yourself properly, you will have a thorough and correct understanding about what you can and what you can't. So you will set proper objective. Because you are very clear about your ralph lauren polo and disadvantage, you will develop what you are good at and avoid what you cannot. In this way, success will not always beyond your reach. Being rewarded from time to time, life will be sunny every day.If you are a cat, no matter you find a tiger or lion in the mirror, you cannot boast yourself the king of the animal world. The only thing you can do is to paw at a mouse. Seeing very clearly in the mirror that you are a cat, you will get clear that you are competent for catching a mouse rather than a goat or deer.
