Air quality 5 click

Air quality 5 click is a triple MOS sensor on a single Click boardâ„¢, which can detect gas pollution for a number of different gases. The onboard sensor is specially designed to detect the pollution from automobile exhausts, as well as the gas pollution from the industrial or agricultural industry.

Click library

Software Support

We provide a library for the Airquality5 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.

Library Description

This library contains API for Airquality5 Click driver.

Examples Description

This application can detect gas pollution for a number of different gases.

The demo application is composed of two sections :

Application Init

Initializes device and configuration chip.

void application_init ( void )
{
log_cfg_t log_cfg;
airquality5.data_config = 0x8583;
log_cfg.level = LOG_LEVEL_DEBUG;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
AIRQUALITY5_MAP_MIKROBUS( cfg, MIKROBUS_1 );
airquality5_init( &airquality5, &cfg );
}

Application Task

Reads the values of CO, NH3 and NO2 sensor and logs data on USBUART every 500ms.

void application_task ( void )
{
uint16_t NO2_sensor_data;
uint16_t NH3_sensor_data;
uint16_t CO_sensor_data;
CO_sensor_data = airq5_read_sensor_data( &airquality5, AIRQ5_DATA_CHANNEL_CO );
NO2_sensor_data = airq5_read_sensor_data( &airquality5, AIRQ5_DATA_CHANNEL_NO2 );
log_printf( &logger, " NO2 data: %d\r\n", NO2_sensor_data );
NH3_sensor_data = airq5_read_sensor_data( &airquality5, AIRQ5_DATA_CHANNEL_NH3 );
log_printf( &logger, " NH3 data: %d\r\n", NH3_sensor_data );
CO_sensor_data = airq5_read_sensor_data( &airquality5, AIRQ5_DATA_CHANNEL_CO );
log_printf( &logger," CO data: %d\r\n", CO_sensor_data );
log_printf( &logger, " -------- ");
Delay_ms( 200 );
}

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.
