Zigbee technology introduction:
Zigbee, as a low-power, low-cost, and high-reliability wireless communication technology, is very suitable for the Internet of Things (IoT). It operates in the 2.4GHz frequency band, adopts the IEEE 802.15.4 standard, and can support a large number of devices to be networked. Zigbee has been widely used in smart cities, smart homes, industrial automation, environmental monitoring, smart agriculture and other fields with its excellent network management capabilities, low power consumption characteristics and wide device compatibility.
Introduction to Mesh Self-organizing Network:
A major highlight of the Zigbee network is that it has the characteristics of Mesh self-organizing network. Mesh network means that each Zigbee device can act as a router to receive and send data packets to form a multi-path communication network. This structure improves the reliability of the entire network and can also increase the coverage to a certain extent. For example, if one of the nodes fails, other nodes can search for nearby normal nodes for data transmission, and the network passing through this node will not be paralyzed due to the failure of one node, ensuring the stable operation of the entire network.
Zigbee module introduction and advantages:
Both HY-52P101P and HY-52P701P modules use TI CC2652 chip, which is a micro wireless module with integrated Zigbee communication protocol stack and supports the latest protocol Zigbee3.0. It is convenient for developers to quickly build Zigbee network. This module usually has the characteristics of low power consumption, small size, easy integration, supports multiple interfaces and protocols, and can easily access various terminal devices.
The advantages of the above two modules are:
Good compatibility: supports Zigbee3.0 standard specification and is compatible with most Zigbee devices on the market.
Security: The module supports centralized security access and distributed security access. At the same time, it supports 128-bit AES encryption to ensure the security of data transmission.
Small size and easy to integrate: The size of the module is 28.7*17.5*2.7mm, and the small size is convenient for integration with various devices.
Strong environmental adaptability: The operating temperature is -40℃~+105℃, which can adapt to most indoor and outdoor application scenarios in different seasons.
Low power consumption: The sleep/wake-up mechanism greatly extends the service life of the device.
High reliability: The Mesh network structure ensures the stability and reliability of data transmission.
Wide coverage: The communication distance of the module can reach more than 500m, supports multi-hop communication, and realizes wireless connection over longer distances.
Large-capacity network: It can support 200 network nodes, support up to 16 routers for networking, and each parent device supports 18 terminal devices directly connected to meet the needs of large-scale Internet of Things applications.
HY-52P101P and HY-52P701P modules are widely used in the following fields:
1. Smart home: including the connection of smart lighting, smart sockets, smart thermostats, smart door locks, smart home appliances and other devices.
2. Industrial automation and control: It can be used to monitor industrial parameters such as temperature, humidity, pressure, and realize remote control of equipment, strengthen operation management, reduce costs, and improve efficiency.
3. Smart city: connect urban infrastructure such as smart street lights, trash cans, parking sensors, etc.
4. Healthcare: wearable devices, medical sensors, and remote health monitoring devices, etc.
5. Agricultural IoT: collect environmental data and transmit it to the control center in real time to achieve remote automation of irrigation, fertilization, temperature and humidity maintenance, etc.
6. Consumer electronics: such as remote controls, smart speakers, and smart TVs, etc.
7. Other areas: road signs, safe driving, etc.
Successful cases of Zigbee modules:
A photovoltaic power plant in the southwest uses the HY-52P101P module as a communication module to connect various photovoltaic panels. The control room uses the light data to control the angle of the photovoltaic bracket in real time, adjust the solar panel in real time, maximize the efficiency of the entire photovoltaic system, and monitor the status of the photovoltaic bracket and solar panel, such as efficiency, power generation, etc., and can find faulty equipment at the first time for timely processing.
