Temp&Hum 12 Click is a smart environmental temperature and humidity sensor Click board™, packed with features which allow easy and simple integration into any design that requires accurate and reliable humidity and temperature measurements.
We provide a library for the TempHum12 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 TempHum12 Click driver.
Config Object Initialization function.
void temphum12_cfg_setup ( temphum12_cfg_t *cfg );
Initialization function.
TEMPHUM12_RETVAL temphum12_init ( temphum12_t ctx, temphum12_cfg_t cfg );
Click Default Configuration function.
void temphum12_default_cfg ( temphum12 *ctx );
Temperature data
float temphum12_get_temperature ( temphum12_t *ctx, uint8_t temp_in );
Relative Huminidy data
float temphum12_get_humidity ( temphum12_t *ctx );
Interrupt state
uint8_t temphum12_get_intrrupt_state ( temphum12_t *ctx );
This application measures temperature and humidity.
The demo application is composed of two sections :
Initializes driver init and configuration device for measurement.
void application_init ( void )
{
log_cfg_t log_cfg;
temphum12_cfg_t cfg;
uint16_t tmp;
uint8_t read_reg [ 2 ];
/**
* 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.
temphum12_cfg_setup( &cfg );
TEMPHUM12_MAP_MIKROBUS( cfg, MIKROBUS_1 );
temphum12_init( &temphum12, &cfg );
temphum12_default_cfg( &temphum12 );
Delay_ms ( 1000 );
Delay_ms ( 500 );
log_printf( &logger, "--- Start measurement ----\r\n" );
}
Reads Temperature and Humidity data and this data logs to the USBUART every 1 sec.
void application_task ( void )
{
float temperature;
float humidity;
temperature = temphum12_get_temperature( &temphum12, TEMPHUM12_TEMP_IN_CELSIUS);
log_printf( &logger, "Temperature: %.2f \r\n", temperature );
Delay_1sec( );
humidity = temphum12_get_humidity( &temphum12 );
log_printf( &logger, "Humidity: %.2f \r\n", humidity );
log_printf( &logger, "-----------------------------\r\n" );
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.
