If the Internet of Things is a spider web that connects various smart terminal devices, then the WiFi module is the strands of spider silk, which is the channel for wireless connection of each device.
As long as you use smart terminal devices in your life, you still need to use WiFi. The existing quantity and popularity of WiFi have advantages that other wireless technology protocols cannot match.
With the rapid development of the Internet of Things, the Internet of Things has become more and more mature in the fields of sharing economy, smart home, smart security, smart medical care, and smart transportation, covering every corner of our lives.
In the era of the Internet of Things, the communication between machines is through wireless communication technology. Currently, the most widely used wireless communication technologies are WIFI, Bluetooth, NFC, etc. Among them, the most popular one is the WIFI module with wide coverage and fast transmission speed. 
As the first step in the application of the Internet of Things, WiFi modules are widely used in the field of smart homes, and the connection between things is the most important thing. WiFi modules are the most important basic products in connection technology.
Highly integrated WiFi chip, with low power consumption and high throughput, is widely used in smart home battery devices, network cameras, peepholes, doorbells, smart security and other fields.
ESP32-S3 can connect physical devices to WIFI wireless network to achieve the purpose of networking. It is now commonly used in smart home, smart transportation, industrial control, smart home appliances, smart buildings, smart factories and other fields.
The ESP32-S3 chip integrates 2.4GHz Wi-Fi and Bluetooth 5 (LE), equipped with Xtensa® 32-bit LX7 dual-core processor, the main frequency is up to 240MHz, built-in 512KB SRAM (TCM), has 45 programmable GPIO pins and rich Communication Interface.
ESP32-S3 MCU adds vector instructions for accelerating neural network calculation and signal processing, which can realize high-performance image recognition, voice wake-up and recognition applications.
It can provide AI interactive functions such as voice recognition and voice control, and solutions such as face detection and recognition. It also develops ESP-MESH networking technology based on the WiFi protocol to meet the needs of smart devices for interconnection functions in IoT application scenarios.
ESP32-S3's Wi-Fi and Bluetooth LE radios have superior radio performance and can work stably at high temperatures. Equipped with an ultra-low power coprocessor (ULP), it supports a variety of low-power modes, and is widely applicable to various low-power application scenarios.
In the wireless communication technology of the Internet of Things application, the WIFI module has its own unique advantages. WIFI modules can provide the data volume, power efficiency and cost required by IoT applications through cross-vendor interoperability, and realize wireless connection functions, which is a function that other wireless communication technologies do not have.
It plays an important role in providing data transmission, video and image transmission, wireless network, intelligent control, and is an important choice for Internet of Things connection.
