Temp-hum 11 Click is a temperature and humidity sensing Click board™, equipped with the HDC1080, a high accuracy digital humidity, and temperature sensor. Its key features are its low power consumption, and the measurement accuracy achieved with that much energy.
We provide a library for the TempHum11 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 TempHum11 Click driver.
Config Object Initialization function.
void temphum11_cfg_setup ( temphum11_cfg_t *cfg );
Initialization function.
TEMPHUM11_RETVAL temphum11_init ( temphum11_t ctx, temphum11_cfg_t cfg );
Click Default Configuration function.
void temphum11_default_cfg ( temphum11_t *ctx );
This function reads temperature data in desired unit.
float temphum11_get_temperature ( temphum11_t *ctx, uint8_t temp_in );
This function reads relative huminidy data
float temphum11_get_humidity ( temphum11_t *ctx );
This function reads data from the desired register.
uint16_t temphum11_read_data ( temphum11_t *ctx, uint8_t reg );
This Click has two sensors which can be set to sample measurements with the resolution of 8, 11 or 14 bits, based on the measurement time. Calibration coefficients that are applied to the measured value and the results are stored in the MSB/LSB format, on the output registers. These values are then used in formulas so that the final temperature or relative humidity data can be calculated.
The demo application is composed of two sections :
Initializes driver init, test comunication and configuration chip for measurement.
void application_init ( void )
{
log_cfg_t log_cfg;
temphum11_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.
temphum11_cfg_setup( &cfg );
TEMPHUM11_MAP_MIKROBUS( cfg, MIKROBUS_1 );
temphum11_init( &temphum11, &cfg );
// Test comunication
if ( temphum11_read_data( &temphum11, TEMPHUM11_REG_DEVICE_ID ) == TEMPHUM11_DEVICE_ID )
{
log_printf( &logger, "--- Comunication OK!!! ---\r\n" );
}
else
{
log_printf( &logger, "--- Comunication ERROR!!! ---\r\n" );
for ( ; ; );
}
temphum11_default_cfg( &temphum11 );
log_printf( &logger, "--- Start measurement --- \r\n" );
Delay_ms ( 500 );
}
Reads Temperature and Humidity data. This data logs to USBUART every 1500ms.
void application_task ( void )
{
temperature = temphum11_get_temperature( &temphum11, TEMPHUM11_TEMP_IN_CELSIUS );
log_printf( &logger, " Temperature : %.2f\r\n", temperature );
humidity = temphum11_get_humidity( &temphum11 );
log_printf( &logger, " Humidity : %.2f\r\n", humidity );
log_printf( &logger, "-----------------\r\n" );
Delay_ms ( 1000 );
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.
