In the field of smart home equipment applications, we will continue to increase and improve the health and environmental protection functions and the development of related IoT wireless modules. Highly integrated, small-sized, low-power and high-performance IoT wireless modules will be used in smart home device development in the future. It will become an increasingly critical factor. In order to realize the purification function and environmental monitoring function of the smart home appliance air purifier for more rooms, the IOT wireless module of a single communication method has been unable to meet its needs, so the data acquisition and processing combined with the combination of WiFi and Bluetooth two communication methods. Will be adopted in more and more smart home products.
Air purification scheme based on WG222
Clear air purification plan design purpose:
A healthy and safe living environment has always been respected. In order to build a more healthy and comfortable home environment, many families have begun to access air purifiers. However, in today's extremely complex indoor home environment, we need to comprehensively consider the study and master bedroom. The air purification needs of each room, such as the second bedroom, guest room, and living room, and the air purifiers are set in different modes according to the environmental monitoring results such as temperature, humidity, and air quality of each room, thereby ensuring the cleanliness of each room environment.
Air purification plan design ideas:
Under the premise of ensuring safety and environmental protection, the following purification requirements can be met: Users can understand the air quality of each room through the mobile phone APP, and adjust the operation mode of the air purifier according to the environmental monitoring data of each room; Remote control of air purifiers. Meeting the purification requirements of different rooms and different air quality, this is an important function development for air purifiers, and these functions can be achieved through the WiFi+Bluetooth 2-in-1 module.
Air purification program works:
Place a home indoor air detector with a built-in BLE Bluetooth module in each room, and place an air purifier with a built-in WiFi+Bluetooth module WG222 in a place with less obstacles in each room. The BLE Bluetooth module in the air detector transmits the environmental monitoring results such as temperature, humidity, and air quality collected in each room to the Bluetooth in the air purifier. The Bluetooth then transmits the data to the WiFi through the serial communication method, and the WiFi uploads the data. To the cloud server, the user can read the environmental monitoring results through the mobile phone APP and set the operating mode of the air purifier.
Application of WiFi+Bluetooth Module WG222 in Air Purifier
The WiFi part of the WiFi+Bluetooth module WG222 is the same as the role of the WiFi module WU106 in the smart home. It is responsible for uploading relevant data to the cloud for remote control or connection to home routers and home control. The Bluetooth part communicates with the device transparently and transmits the relevant information to WiFi.
Air purification program description:
In the design of air purifiers, the WiFi+Bluetooth combo module WG222 is added, and a home indoor air detector equipped with a built-in BLE Bluetooth module can be used to control the air purifier through smart phones, whether it is at home or not. Still on the way home, the mobile phone is a little lighter, and the quality control of the home environment is more intelligent, and it truly becomes the umbrella of the public's healthy life.
WiFi + Bluetooth combo module WG222:
WG222 is a highly integrated WiFi / BLE combo module with application processor, low power 1x1 802.11n dual band WiFi, Bluetooth and power supply. It also includes many peripherals including UART, I2C, SPI, I2S, PWM, IrDA, and auxiliary ADC. Embedded SRAM / ROM included. WiFi wireless protocol: 802.11a / b / g / n, baseband and MAC, designed to meet low-power and high-throughput applications. This module only requires an external 3.3V power supply.
