Library Description
The library carries all necessary functions to have complete control over Air quality 3 click.
Key functions
void airq3_getCO2andTVOC( uint16_t *algData ) - Read Co2 and TVOC values.
void airq3_setMeasurementMode( uint8_t mode ) - Set measurement mode.
void airq3_init() - Default module initialization must be called before module usage.
Examples Description
The demo application is composed of three sections:
void applicationTask()
{
airq3_getCO2andTVOC(&AIRQ3_Data[0]);
ByteToStr(AIRQ3_Data[0],text);
mikrobus_logWrite("CO2 value : ",_LOG_TEXT);
mikrobus_logWrite(text,_LOG_TEXT);
mikrobus_logWrite(" ppm",_LOG_LINE);
ByteToStr(AIRQ3_Data[1],text);
mikrobus_logWrite("TVOC value : ",_LOG_TEXT);
mikrobus_logWrite(text,_LOG_TEXT);
mikrobus_logWrite(" ppb",_LOG_LINE);
Delay_1sec();
}

Additional notes and information
Depending on the development board you are using, you may need USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
