NO2 Click is a very accurate nitrogen-dioxide gas sensor Click board™, equipped with the SPEC amperometric gas sensor which electrochemically reacts with the nitrogen-dioxide (NO2).
We provide a library for the No2 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 No2 Click driver.
Config Object Initialization function.
void no2_cfg_setup ( no2_cfg_t *cfg );
Initialization function.
NO2_RETVAL no2_init ( no2_t ctx, no2_cfg_t cfg );
Click Default Configuration function.
void no2_default_cfg ( no2_t *ctx );
Device Enable function
void no2_enable ( no2_t *ctx, uint8_t state );
Function for read ADC sensor data
uint16_t no2_read_adc ( no2_t *ctx );
Get NO2 Data function
float no2_get_no_2_ppm ( no2_t *ctx );
This application measures NO2.
The demo application is composed of two sections :
Initializes I2C driver and device configuration.
void application_init ( void )
{
log_cfg_t log_cfg;
no2_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.
no2_cfg_setup( &cfg );
NO2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
no2_init( &no2, &cfg );
no2_default_cfg( &no2 );
log_printf( &logger, "NO2 is initialized \r\n" );
Delay_ms ( 300 );
}
Gets NO2 (Nitrogen dioxide) data as ppm value and logs to USBUART every 500ms.
void application_task ( void )
{
float no2_value;
no2_value = no2_get_no_2_ppm( &no2 );
log_printf( &logger, "NO2 value : %.2f ppm \r\n", no2_value );
Delay_ms ( 500 );
}
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.
