Modern security monitoring is increasingly being valued. It is generally composed of image acquisition, transmission and storage system. The use of high-precision cameras with advanced image processing technology and transmission technology. Although its security monitoring performance is very good, but there are large investment costs, real-time alarm performance is poor. Large amount of data, the shortcomings of concealment. In view of these shortcomings, some applications can also use infrare

This section and the next section will tell about the low power consumption of ZigBee terminal equipment.
This section focuses on the low-power theory portion of ZigBee technology based on the CC2530 chip.
First, the application of the background

Writing a pleasing engineering document is a difficult task. If you want to write well, not only to use the tool (using the right tools), pay attention to writing, but also have to devote a lot of time, really is a very difficult thing. But, if really write good, also is good great Yan: can let a person understand "why so design", namely "know it more know its why", also can peel off some trivial details, let more not so much time and energy, or the background knowledge insufficient friend, to t
A project recently involved in planning requires a large amount of ZigBee (about 5000) data collection. Because of the wide-area layout and the mesh network architecture, many nodes are so-called routing nodes, which raises a problem. The routing node usually needs continuous power supply, because only batteries can be used for power supply in the field, this is in great conflict with the Requirements for battery use for one to two years. Therefore,
With the rapid development of wireless communication technology, the demand for short-distance wireless communication technology is becoming more and more urgent. ZigBee is a new type of short-distance, low-speed wireless communication technology, which is a wireless remote technology and Bluetooth between the technical solution. Using multiple ZigBee modules to form a multi-level trunk self-organizing netw
Wireless networks are a huge family. Various wireless technologies have different application aspects. Since its development, wireless networks are also different. In addition to Bluetooth, the short-distance wireless Branch also has a wireless ZigBee technology.
Wireless ZigBee technology is a new wireless network technology with low complexity, low power consumption, low data rate, and low cost. It is a t

Industrial control engineers need to use ZigBee technology? You do not need to become an RF expert!
Both Zigbee and IEEE 802.15.4 are low-speed wireless network standards, which can save expensive and easily damaged connections in industrial control products. In this way, liquid or process control equipment can be placed at will and can still communicate with other systems. Because the network has no requi

ZigBee Technology is a short-distance, low-power wireless communication technology. It is characterized by close range, low complexity, self-organization, low power consumption and low data rate. It is mainly suitable for automatic control and wireless remote controlling, and can be embedded in various electronic devices. In short, ZigBee chip is a cheap, low-power, near-range wireless ad-network communicat
of a large number of network cabling, high installation and maintenance costs, poor reliability, and even in some structures can not achieve cabling. With the development of sensor technology,ZigBee Digital Transmission Module communication technology and MEMS Technology, wireless sensor technology has been developed and can overcome the cabling capacity and high cost of wired sensor network, and in practical application
