In the past few years, smart home equipment explosion growth. Things who have been known as "home automation" and still known as "IoT" have now become a more friendly category, we call smart home. We have almost all heating, lighting, camera, sensors, and new devices that will appear every week to move your home to a future.

In the past few years, we have changed from a disconnected system into a world with emerging centers, such as large devices such as Amazon Echo and Google Home as hubs connect all connected services together, as well as Apple and other emerging Platform homekit and Samsung Smartthings. So what role does Zigbee play in a brave new world in smart home? Smart home, all the ideas behind smart home is to keep everything in touch with all things, so you keep abreast of the situation while you keep notice. This may be your lighting with your secure camera, or your smart coffee machine opens when you get up. The Internet of Things may be a quite useless term, but in fact, this is what is happening, everything is connected, which means that information can be shared, your life can be controlled without having to access everything alone.
If you look from a broad building, smart home equipment is mainly used in smart buildings. The intelligent building industry has great development potential, and it is considered to be a very important industry in my country's economic development. Its industry's driving role is not to be underestimated. According to statistics, the proportion of intelligent buildings account for 70% of new buildings, and Japan is 60%. In 2015, my country's intelligent building accounted for about 30% of the proportion of new buildings. my country's smart building started in 1990, 6 years later than the United States, 4 years later than Japan, through comparison of the development of the US and Japanese intelligent buildings, is expected to maintain 3 percentage points per year in my country's smart buildings in China. The speed of the left and right, in 2021, my country's smart buildings are expected to reach 57% in new construction. From a narrow smart home equipment application, it is mainly concentrated in the commodity residential market, with the application ratio of villas and high-end apartments in a high level. If the annual housing is completed, my country's new product residential intelligent home equipment industry market scale prediction is shown in 2016-2011.
Dafin Dading Group, in response to the current smart home market, launched the NXP JN5189 ZigBee intelligent switch panel scheme, which has functions that can match the APP custom action, freely manipulate other products, indicator feedback, with ZigBee 3.0 specification And other manufacturers' products are interoperable, low power consumption, long transmission distance, self-assessing, low levels, low cost, short development cycle, have low power low cost in the market.
The NXP JN5189 peripheral circuit is simple, only the crystal and a small amount of capacitance can build the minimum system, the internal Balun single-RF output and up to 10 dB transmit power saves the cost of the RF circuit design and external PA.
Solution hardware design architecture:
Main platform choice
The main platform of this zigbee switch panel application is NXP JN5189, which has high performance, low cost, easy development characteristics, and this platform is
1 Cortex M4 kernel, low power consumption, stable operation.
2 The maximum emission power is +10 dBm, and the transmission distance is far.
3 The radio frequency circuit and the internal circuit are fully optimized, and the reception power consumption is half ahead of the previous generation.
4 The operating voltage is large, and the battery usage time is extended.
5 Stable NXP Zigbee 3.0 protocol stack, complete application layer software DEMO, shorten customer development cycles.
6 Use the free IDE MCUXPRESSO provided by NXP for software development, safe and efficient.
7 Chip prices have advantages than similar products.
