Temp-Hum 9 Click is a smart temperature and humidity sensing Click board™, packed with features that allow simple integration into any design.
We provide a library for the TempHum9 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 TempHum9 Click driver.
temphum9_cfg_setup
Config Object Initialization function.
void temphum9_cfg_setup ( temphum9_cfg_t *cfg );
temphum9_init
Initialization function.
err_t temphum9_init ( temphum9_t *ctx, temphum9_cfg_t *cfg );
temphum9_get_temperature
Calculating temperature
float temphum9_get_temperature ( temphum9_t *ctx, uint8_t data_mode );
temphum9_get_humidity
Calculating relative humidity
float temphum9_get_humidity ( temphum9_t *ctx, uint8_t data_mode );
temhum9_get_data
Calculating temperature and relative humidity
void temhum9_get_data ( temphum9_t *ctx, uint8_t data_mode, float *temp, float *hum );
This example demonstrates the use of TempHum 9 Click board by reading and displaying the temperature and humidity measurement results.
The demo application is composed of two sections :
Initializes I2C driver and sends SLEEP and WAKEUP commands.
void application_init ( void )
{
log_cfg_t log_cfg;
temphum9_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.
temphum9_cfg_setup( &cfg );
TEMPHUM9_MAP_MIKROBUS( cfg, MIKROBUS_1 );
temphum9_init( &temphum9, &cfg );
Delay_ms ( 100 );
temphum9_send_command( &temphum9, TEMPHUM9_SLEEP );
Delay_ms ( 500 );
temphum9_send_command( &temphum9, TEMPHUM9_WAKEUP );
Delay_ms ( 500 );
log_info( &logger, " Application Task " );
}
Performs simultaneous temperature and relative humidity measurements and logs both values on the USB UART once per second.
void application_task( )
{
float temperature = 0;
float humidity = 0;
temhum9_get_data ( &temphum9, TEMPHUM9_NORMAL_MODE, &temperature, &humidity );
log_printf( &logger, " Temperature: %.2f degC\r\n", temperature );
log_printf( &logger, " Relative humidity: %.2f %%\r\n", humidity );
log_printf( &logger, "-----------------------------\r\n" );
Delay_ms ( 1000 );
}
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.
