In the Internet of Things (IoT) Internet of Things, WiFi technology that allows electronic devices to connect to a wireless local area network (WLAN) naturally becomes a must. Serial WiFi, thanks to its convenient networking capabilities, has allowed many traditional device manufacturers to see the hope of entering the Internet of Things. WiFi module selection application in addition to the communication interface, because its power consumption value directly related to the electronic equipment standby time, so there are engineers more biased towards the choice of low-power WiFi module.
In the previous article, “Selection of WiFi Modules in WiFi Solutionsâ€, Xiao Bian also made some sorts of problems in the selection of WiFi modules. In this article, SKYLAB will focus on analyzing the functions of the small-size low-power WiFi module WG219 and application.
Small Size Low Power WiFi Module WG219
WG219 is a low-power (deep sleep mode current 18uA) size UART-WiFi passthrough module based on the ESP8266 chip. It complies with the 802.11b/g/n wireless module standard and is designed for mobile devices and IoT applications. The user's physical device is connected to a WiFi wireless network, performs Internet or LAN communication, and achieves networking functions. In addition, the WG219 only needs to use the AT command to control the output through the serial port, which can meet most of the network functional requirements.
The WiFi module WG219 supports rapid program development applications for ultra low power devices with SW on-chip complete applications. This makes the WG219 a good choice for highly integrated, low-power automation and sensor solutions.
WG219 is optimized for enterprise, smart grid, home automation and control client applications, and under the conditions of limited data transmission and reception control, to provide customers with secure, stable, simple and rapid development of wireless applications of the Internet of Things, shorten product development cycle.
WG219 working mode: Support STA/AP/STA+AP working mode;
Lowest power consumption of WG219: deep sleep hold current is 0.018mA
Application of WG219: It can be used in IoT applications that require serial transmission, such as smart socket, intelligent light control, mesh network (WiFi Mesh), industrial wireless control, sensor network, home automation, security ID tag, WiFi probe, WiFi hotspot ads, etc.
