Hexiwear
Very advanced Click Air Quality example for Hexiwear featuring OLED Display, Bluetooth, Cloud and Touch
Dependencies: Hexi_KW40Z Hexi_OLED_SSD1351
This project has been developed by mbed user daveyclk
This project demonstrates the use of the Mikroelektronika Click Air Quality module with hexiwear featuring the OLED display, the Bluetooth for Cloud connectivity and Touch buttons
Plug Hexiwear into the Docking Station and the Air Quality Click to the Click Socket 1
Connect the USB cable to your computer and to the micro-USB port of the Docking Station
Compile the project and copy the binary "Hexi_Click_AirQuality_Example_HEXIWEAR.bin" in the DAP-LINK drive from your computer file explorer
Press the K64F-RESET button on the docking station to start the program on your board
The OLED screen will display some graphics and the Air Quality measurement in ppm below
Blow gently on the sensor and see the value changing
Graphic displayed will move the Arrow from Green to Purple depending from the ppm value measured by the Air Quality sensor
Download the cell phone App Hexiwear from iOS or Android stores to connect your board to your phone
Type the pin displayed on the screen and give a name to your board to pair it via the App
Congratulation your data are now streamed directly to Wolkabout Cloud...
To visualize the data remotely (over cloud not bluetooth), you can go to Wolksense.com or download the Wolksense iOS/Android App and login with same account
