Hexiwear / Mbed OS Hexi_Click_IRThermo_Example

Very advanced Click IR Thermo example for Hexiwear featuring OLED Display, Bluetooth, Cloud and Touch

Dependencies:   Hexi_KW40Z Hexi_MLX90614 Hexi_OLED_SSD1351

Fork of Hexi_Click_IRThermo_Example by Hexiwear

This project has been developed by mbed user daveyclk

This project demonstrates the use of the Mikroelektronika Click IRThermo module with hexiwear featuring the OLED display, the Bluetooth for Cloud connectivity and Touch buttons

Plug Hexiwear into the Docking Station and the IRThermo 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_IRThermo_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 temperature measurement below
Approach your end from the IRThermo sensor and see the temperature changing
Graphic displayed will change from blue, orange or red depending from the temperature measured by the IR Thermo 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
