Air purification scheme based on WG222
In the field of smart home devices, there is a growing emphasis on enhancing health and environmental protection features. The development of advanced IoT wireless modules plays a crucial role in this evolution. Future smart home devices will increasingly rely on highly integrated, compact, low-power, and high-performance IoT modules to improve functionality and user experience.
To support more comprehensive air purification and environmental monitoring across multiple rooms, single-communication IoT modules are no longer sufficient. As a result, smart home products are adopting dual-communication solutions that combine WiFi and Bluetooth technologies. This approach enables more efficient data acquisition, processing, and real-time control, making it possible for users to monitor and adjust air quality remotely via mobile apps.
The air purification solution based on the WG222 module is designed to meet these evolving needs. It allows users to access real-time air quality data from each room through their smartphones, enabling them to customize the operation mode of air purifiers according to specific environmental conditions. This not only improves air quality but also enhances comfort and safety within the home environment.
The core idea behind the design is to ensure seamless connectivity and intelligent control. By placing an indoor air detector with a built-in BLE module in each room and positioning an air purifier equipped with a WiFi+Bluetooth WG222 module in areas with minimal signal interference, the system can effectively collect and transmit environmental data. The BLE module sends information such as temperature, humidity, and air quality to the purifier’s Bluetooth module, which then forwards the data via serial communication to the WiFi module for cloud upload. This allows users to monitor and manage air quality from anywhere.
The WG222 module is a highly integrated solution that combines WiFi and Bluetooth capabilities. It includes an application processor, low-power 1x1 802.11n dual-band WiFi, Bluetooth, and power management. It also features various peripherals like UART, I2C, SPI, I2S, PWM, IrDA, and auxiliary ADC, along with embedded SRAM and ROM. This makes it ideal for low-power, high-throughput applications in smart home environments.
With the WG222 module, air purifiers become more intelligent and user-friendly. Whether at home or on the go, users can easily monitor and control their indoor air quality through a mobile app, ensuring a healthier living space. This technology represents a significant step forward in smart home innovation, offering a reliable and efficient solution for modern households.
