Application of dual-core BLE WiFi module in air purifier

Wireless communication technologies based on WiFi protocol, BLE protocol and ZigBee protocol create unlimited possibilities for smooth communication between objects, between people and objects, and even between people and nature in various fields such as production, medical treatment, home, environmental testing, public safety, etc. In recent years, with the serious haze and pollution, the demand for air purifiers has expanded unprecedentedly. In response to the requirements of smart homes, we have developed and launched a high-quality WiFi + BLE technology two-in-one combination wireless module for the wireless communication needs of IoT companies. So how does this dual-core WiFi BLE module work in IoT applications?

Terminal perception: embed sensors into places, objects and systems that need to be paid attention to and collected, and obtain key feature values and information flows in real time.

Network connection: build ubiquitous network connections and support IPv6 to provide a large number of IP addresses for various mobile terminals.

Background computing: use new computing and processing systems such as cloud computing to process information and assist in decision-making.

WiFi protocol + BLE protocol two-in-one combination IoT module

The WiFi module, BLE module, and GPS module we are familiar with are all wireless data transmission module products based on one communication method, while the combination module is based on two or more module products. The WiFi technology + BLE BLE technology two-in-one combination module supports multiple data interfaces of WiFi and BLE BLE. The WiFi interface is divided into UART interface and SDIO interface. The WiFi module and the BLE module can transmit data through UART serial communication. It has high integration and combines the advantages of WiFi and BLE wireless communication technologies, providing a complete solution for customer devices to achieve WiFi networking and rapid application development.

IoT module smart air purifier solution hardware combination:

(1) Mobile app software: users connect to the cloud through 3G/4G/wifi and remotely control the air purifier at home on the mobile phone

(2) Cloud server: responsible for storing air quality data and executing user control instructions

(3) BLE + WiFi combination module: responsible for receiving air quality data transmitted by the BLE module and uploading it to the cloud

(4) Air detection sensor with embedded ble BLE module: arranged in each room, responsible for collecting temperature, humidity and air quality (pm2.5, etc.)

Air purification solution in smart home: mainly relying on ESP32 chip WiFi protocol + BLE protocol two-in-one combination dual-core module. The ESP32 chip series dual-core WiFi BLE module is connected to the main control board circuit of the smart air purifier solution. The air sensor with the built-in ble BLE module is responsible for automatically collecting the temperature, humidity and air quality of each room in real time. The data is transparently transmitted to the ble BLE part of the ESP32 chip through the ble BLE module, and the air quality data transmitted is then transmitted to the WiFi part through the serial port inside the ESP32.

The WiFi module is responsible for uploading air quality data to the cloud, and the mobile phone app can remotely connect to the cloud through 3G/4G/wifi to remotely control the purifier to strengthen or weaken according to its own needs. In this way, whether the user is at home or on the way home from school, he can control the environmental quality of his home through his mobile phone.
