As IoT technologies and products are increasingly used in logistics, transportation, security, energy, medical, construction, manufacturing, home furnishing, retail and other industries, they are being upgraded from personal consumption to industrial control. The application of WiFi smart socket solutions has gradually spread from the field of smart homes to other fields. Recently, I have encountered many engineers asking questions related to the smart socket WiFi module. Here, the editor will answer one by one on the application of the SKYLAB WiFi module in the smart socket.
Wi-Fi smart socket solution based on WG219
First introduce the working principle of the WiFi smart socket that engineers are most concerned about: the UART WiFi module is built in the smart socket, the user’s mobile phone downloads the relevant APP, and the router connects to the WiFi to establish a connection with the WiFi module in the smart socket to obtain the control authority of the smart socket. It can be controlled through the cloud.
Let’s take a look at the UART WiFi module: The module integrates radio frequency transceiver, MAC, baseband processing, WiFi protocol and configuration information and network protocol stack, which can connect the user’s physical device to the WiFi wireless network for Internet or LAN communication. Networking function. Users can use it to easily realize the wireless network function of serial devices, save development time, make products put into the market faster, and enhance competitiveness. UART WiFi module is mainly used in smart grid, smart transportation, smart home, handheld devices, industrial control and other fields.
At present, there are many mature WiFi smart socket solutions on the market. Most of them are based on UART WiFi modules. WU106 and WG219 are two commonly used smart socket WiFi modules. New smart sockets will be launched in the near future. WiFi module, stay tuned.
The last problem of WiFi module selection that engineers pay attention to: how to judge whether the smart socket is suitable for UART WiFi module
(Reminder: Smart sockets that meet the following three conditions are suitable for UART WiFi modules)
Communication interface with WiFi module—UART
Product main chip-MCU (Single Chip Microcomputer)
Product operating system-no embedded operating system
UART WiFi module WU106, WG219
Attached is the selection table of UART WiFi module WU106 and WG219, hoping to help engineers who are choosing WiFi module for WiFi smart socket solution.
