In the wave of the development of the Internet of Things, the popularity of smart homes continues to heat up. Due to the features of smart homes such as security, energy saving, comfort, convenience, and high efficiency, more and more customers have begun to accept and develop smart home products and systems. The wireless modules based on WiFi, Bluetooth and other single communication methods can no longer meet their needs. Demand, therefore, SKYLAB launched a variety of WiFi + Bluetooth combo modules to achieve the growing demand for wireless communication in the Internet of Things. The protagonist of this article is the WiFi+Bluetooth combo module WG222 that acts on the smart home air purifier solution.
In front of SKYLAB Jun has introduced the application of WiFi + Bluetooth combination module WG222 in the smart home air purifier program.
Smart Home Air Purifier Solution
Among them, the WiFi part of WG222 and the WiFi module WU106 are in the same role as those in the smart home. They are responsible for uploading relevant data to the cloud for remote control or connection with home routers and home control. The Bluetooth part is responsible for collecting data and transmitting relevant information to WiFi, so that users can control the quality of the home environment through their mobile phones, whether they are at home or on the way home.
About WG222
WG222
WG222 is a highly integrated WiFi / BLE combo module with 1x1 802.11n dual-band WiFi, Bluetooth and power management unit. It also includes an ARM Cortex-M4F MCU and many interfaces: UART, I2C, SPI, I2S, PWM, IrDA, and Auxiliary ADCs. Using the MT7697 chip requires only an external 3.3V power supply.
