ESP32-S3 wireless communication chip module in Internet smart home application

The application of smart home electronic products, greatly improves people”s daily life, from early black and white TV, refrigerators, etc., to the current network TV, smart air conditioning, etc., there is no shortage of science and technology progress and the development of the times It also reflects the development trend of contemporary home electronic products from the side, which is to develop toward miniaturization, intelligence, and network, which is benefited from the continuous improvement of electronic chip integration and the rapid development of network communication technology.

At present, in the development of home electronic products, the most use of single-chip control technology and wireless network communication technology. Among them, single-chip control technology is not only applicable to the development of home electronics, but also widely used in industrial, medical, exploration and other fields.

In fact, since the first single-chip microcontroller in the 1980s, the start of the automatic control field has always been an ignored status, by combining it with different sensors and controllers, can design to adapt to various environments. Automated electronics, which can give people a great convenience.

my country”s network communication technology has achieved significant progress in recent decades, from mobile phone SMS, to wireless networking, from 2G, 3G, 4G to 5G communication, network transmission, network transmission, continuous improvement, constantly rich.

One of the two wireless network communication methods, one is GPRS, mainly to mobile Internet communication, the other is Wi-Fi, within its local area network, any communication devices with Wi-Fi functions can pass through it The router is wirelessly connected, and the internet is accessed.

Of course, there are also Bluetooth, Zigbee, NFC, etc., but in the home field, there is no doubt that Wi-Fi dominates, which uses IEEE802.11x series standards, has a wide range of signal coverage, fast transmission rate, application threshold Low feature.

In a home environment, electronic devices developed by this technology can effectively avoid the trouble of wiring, while comparing the GPRS traffic billing method, the transmission of long-term large data volume using Wi-Fi technology can effectively reduce communication rates, so The technology has great advantages in home electronics.

Modern society, people”s quality of life is constantly increasing, and household appliances in the family are increasing, and people are also getting higher and higher for manipulating the convenience of household appliances. Under the Internet, the Wi-Fi wireless home appliance switch control system based on single-chip microcomputer and wireless communication technology can be switched from mobile phone anytime, anywhere, and provide great convenience to people”s lives.

At present, the Internet of Things communication means is Wi-Fi, Bluetooth, ZigBee, power carrier, etc., combined with the characteristics of home environment, we have chosen Wi-Fi communication mode as communication means. First of all, most families have spread Wi-Fi networks, using the existing network to meet the needs, thereby reducing the popularity cost.

Second high-speed Wi-Fi networks can carry larger communication data and more complex encrypted communication means. The third is that the Wi-Fi network has the most widely covered, which can be easily transferred to all parts of the world. Some causes of the Wi-Fi mode as communication means.

Fei Rui Technology Agent Lexin ESP32-S3 wireless communication chip module, this is a low-power MCU system-level chip (SOC), integrated 2.4GHz Wi-Fi and low-power Bluetooth® LEs dual-mode wireless communication Have a complete Wi-Fi subsystem that meets the IEEE 802.11b / g / n protocol, which has three modes of STATION, Softap, and Softap Station.

Low-power Bluetooth subsystems support Bluetooth 5 and Bluetooth Mesh. Industry-leading low-power performance and RF performance • Xtensa® 32-bit LX7 dual-core processor, five-level pipeline architecture, main frequency up to 240MHz. Up to 128-bit data total line width and proprietary SIMD instructions provide superior calculation performance; efficient L1 caches improve the performance performance of external memory.

Powerful storage features: Built-in 512KB SRAM, 384KB ROM storage, and support multiple external SPI, Dual SPI, Quad SPI, Octal SPI, QPI, OPI Flash, and external RAM.

Perfect security mechanism: Hardware encryption accelerator supports AES-128/256, Hash, RSA, HMAC, digital signature, and security boot.

Integrated Real random number generator: Support for access and external memory, supports the plug-in memory card addendum.

Rich communication interfaces and GPIO feet can support multiple scenarios and complex applications.

The ESP32-S3 MCU adds vector instructions for accelerating the work of neural network computing and signal processing, and the MACTOR INSTRUCTIONS. Using these vector instructions via the ESP-DSP and ESP-NN libraries, high-performance image recognition, voice wake-up, and identification can be implemented. Provide easy and simple lifestyle for smart home and smart life.

The smart home system based on Wi-Fi communication technology fully considers the security and expansion of communication, providing intelligent homeland links with a safe, cost, convenient and scalable system. At the same time, I told some families that have been decorated, designing the wiring system, doing plug and play, free to expand.

Under the big tide of all things, smart manufacturing, I believe that the smart home system based on Wi-Fi communication technology will change our lifestyle, and bring infinite convenience to our lives.
