Air quality 3 Click is the air quality measurement device, which is able to output both equivalent CO2 levels and total volatile organic compounds (TVOC) concentration in the indoor environment.
We provide a library for the AirQuality3 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.
This library contains API for AirQuality3 Click driver.
Config Object Initialization function.
void airquality3_cfg_setup ( airquality3_cfg_t *cfg );
Initialization function.
AIRQUALITY3_RETVAL airquality3_init ( airquality3_t ctx, airquality3_cfg_t cfg );
Click Default Configuration function.
void airquality3_default_cfg ( airquality3_t *ctx );
Get CO2 and TVOC data
uint8_t airquality3_get_co2_and_tvoc ( airquality3_t ctx, airquality3_air_data_t air_data );
Temperature and humidity data settings
void airquality3_set_environment_data ( airquality3_t *ctx, uint32_t env_data );
Function for settings sensor drive mode and interrupts.
void airquality3_set_measurement_mode ( airquality3_t *ctx, uint8_t mode );
The demo application shows air quality measurement.
The demo application is composed of two sections :
Configuring Clicks and log objects. Settings the Click in the default configuration. Call the procedure the wakeup function of the chip.
void application_init ( void )
{
log_cfg_t log_cfg;
airquality3_cfg_t cfg;
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.
*/
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
airquality3_cfg_setup( &cfg );
AIRQUALITY3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
airquality3_init( &airquality3, &cfg );
// Wake-up Click procedure
airquality3_set_power( &airquality3, AIRQUALITY3_POWER_STATE_ON );
airquality3_hardware_reset( &airquality3 );
airquality3_app_function( &airquality3, AIRQUALITY3_APP_START );
airquality3_default_cfg( &airquality3 );
Delay_ms ( 500 );
log_info( &logger, "---- Start measurement ----" );
}
Reads CO2 and TVOC value in the air and logs this data on the USBUART.
void application_task ( void )
{
airquality3_air_data_t air_data;
// Task implementation.
airquality3_get_co2_and_tvoc ( &airquality3, &air_data );
log_printf( &logger, "\r\n---- AirQuality data ----\r\n" );
log_printf( &logger, ">> CO2 data is %d ppm.\r\n", air_data.co2 );
log_printf( &logger, ">> TVOC data is %d ppb.\r\n", air_data.tvoc );
Delay_1sec();
}
The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Additional notes and informations
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.
