Application Analysis of smart street lamp ZigBee technology

Application Analysis of smart street lamp ZigBee technology In the dark night, the street lights light up the way forward for everyone. When the night comes, the street lights are lit up. As there are more pedestrians on the road, the darker the sky, the brighter the street lights. When the night begins, when there are few pedestrians on the road, the street lights become darker, saving energy for urban lighting. Figure 1: adjustable lighting So how

New Wi-Fi standard HaLow challenges ZigBee and Z-Wave

New Wi-Fi standard HaLow challenges ZigBee and Z-Wave Applicable to low-power transmission standards of Iot devices, including Bluetooth, ZigBee, Z-Wave, and Thread. Due to the rapid growth of the low-power wireless network communication market, common Wi-Fi standards for home and public hotspots are also released to compete for market cakes. According to the rethinkresearch website, the Wi-Fi Alliance has

ZigBee Protocol __ Wireless sensor network

ZigBee can be divided into three basic levels: Physical layer/Data link layer, ZigBee stack layer and application layer The basic functions of each layer are as follows: (1) Physical layer/Data Link layer: Physical layer and data transmission media, responsible for the transformation of physical media and bits, and the transformation of data bits and upper-layer data frames. The data link layer is responsib

About four ways to bind ZigBee

Binding is a very important concept in ZigBee, presumably we have read a lot of articles, including "ZigBee four kinds of binding method in the Ti_z-stack protocol stack application" most typical, this article I also read several times, receiving quite abundant. In addition to the Feibit forum also has a post explaining the enddevicebinding of the pain of the transmission mechanism, analysis is also quite t

Z-stack sends data by calling function void Sampleapp_sendflashmessage (UInt16 flashtime) in the application layer, where flash time is the data being sent, and this function is invoked in the application afstatus_t af_datarequest (afaddrtype_t *dstaddr, endpointdesc_t *srcep, UInt16 CID, UInt16 len, uint8 *buf

Brief Analysis of ZigBee Wireless Network Design and Application (1)

The ZigBee protocol is a global open standard to provide low-power wireless connections for many applications with test and control functions. ZigBee enhances the functions of 802.15.4 with flexible and scalable network topology, easy-to-install comprehensive settings, smart routing technology, and anti-DDoS capability. ZigBee also has strict security measures an

Connecting In the previous article "ZigBee journey (1): setting up the ground", we briefly introduced Zigbee and the establishment of its development enviro

I read some articles about ZigBee-assignments assigned by the teacher.

In the impression, ZigBee is mainly used in industry, while Bluetooth is used in life. Some consumer products use Bluetooth, such as mobile phones, laptops, wireless mouse, and so on. The assignment assigned by the teacher is based on the sensor network, and he thinks that the ZigBee technology should be used in the sensor network. Many sensors are used in sensor networks. If wired data is used for data tr

ZigBee Learning Path (15): Key experiment based on protocol stack

I. PrefaceAfter the last study, I believe that we have initially learned to use the ZigBee protocol to send and receive data. Today, we're going to experiment with keystrokes and learn how to implement key interrupts in the protocol stack.Two.

Research on Controllable networking methods based on ZigBee Wireless Networks (1)

Research on Controllable networking methods based on ZigBee Wireless Networks (1) ZigBee wireless network application nodes mostly use self-networking to access the network, which may cause excessive consumption of some nodes in the network. In this case, a controllable networking mode is proposed. By selecting and controlling the parent node of a node to access the network, the topology and Node Distribut

ZigBee journey (V): several important cc2430 Basic Experiments-Serial Communication

to get every character received. When this character is not '@', it indicates that the input is not complete. Add the character to the character array recv_buf. When this character is exactly, this indicates that the input is complete. Therefore, every character in recv_buf is sent to the PC in order and recv_count is reset.(5) Experiment Results First, complete the hardware connection and open the serial port debugging tool. The configuration parameters are as follows: Click "open serial port

Build a small Iot Platform Based on ZigBee

Small projects are really tiring. It seems very simple in principle. The underlying equipment transmits data through Zigbee, and the upper layer equipment uses DTU for data communication. However, there is a problem: DTU is a single transmission. When the upper-layer device performs command control, if the underlying device uploads data, the control command will fail, you must strictly control the data upload time and command processing time. The un

ZigBee Learning Notes Chapter One, "Light the first led"

as an Internet of things professional students, feel not to learn these things connected to the knowledge of the Internet can not afford their own, well, learning to start!!! The CC2530 has 21 digital input/output pins, namely p01-p07, P10-P17, P20-P24. In particular, it is important to note that the input and output of the CC2530 pin is different from the 51 single chip microcomputer, look at the comparison of the picture.Well, this has a basic understanding of our own
