Temp&Hum 16 Click is a compact add-on board that represents temperature and humidity sensing solutions. This board features the WSEN-HIDS (252.0.0.50001), a MEMS-based capacitive humidity sensor with an integrated ASIC and I2C and SPI serial communication from Würth Elektronik. A silicon-based temperature sensor is also integrated within the same package. ASIC contains the multiplier, operational amplifier, analog-to-digital converter, and other signal conditioning blocks like controller logics and interrupts. It converts the analog signal from humidity and temperature sensing elements into 16-bit digital humidity and temperature values. The 252.0.0.50001 is factory calibrated for both humidity and temperature measurements with no further calibration required. This Click board™ is an ideal solution to be used in various temperature and humidity-related applications.

We provide a library for the TempHum16 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.
This library contains API for TempHum16 Click driver.
temphum16_cfg_setup
Config Object Initialization function.
void temphum16_cfg_setup ( temphum16_cfg_t *cfg );
temphum16_init
Initialization function.
TEMPHUM16_RETVAL temphum16_init ( temphum16_t *ctx, temphum16_cfg_t *cfg );
temphum16_default_cfg
Click Default Configuration function.
void temphum16_default_cfg ( temphum16_t *ctx );
temphum16_check_ready
Temp&Hum 16 check ready function.
uint8_t temphum16_check_ready ( temphum16_t *ctx );
temphum16_get_humidity
Temp&Hum 16 get humidity function.
err_t temphum16_get_humidity ( temphum16_t *ctx, float *humidity );
temphum16_get_temperature
Temp&Hum 16 get temperature function.
err_t temphum16_get_temperature ( temphum16_t *ctx, float *temperature );
This library contains API for the Temp&Hum 16 Click driver. This demo application shows an example of humidity and temperature measurement.
The demo application is composed of two sections :
Initialization of SPI or I2C module and log UART. After driver initialization and default settings, the app display retrieves the sensor parameters such as temperature and humidity.
void application_init ( void ) {
log_cfg_t log_cfg; /**< Logger config object. */
temphum16_cfg_t temphum16_cfg; /**< Click config object. */
/**
* 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_printf( &logger, "-----------------------\r\n" );
log_printf( &logger, " Start measurements \r\n" );
log_printf( &logger, "-----------------------\r\n" );
}
This is an example that shows the use of a Temp&Hum 16 Click board™. Logs humidity [ % ] and temperature [ degree Celsius ] data. Results are being sent to the Usart Terminal where you can track their changes.
void application_task ( void ) {
if ( temphum16_check_ready( &temphum16 ) == TEMPHUM16_DRDY ) {
temphum16_get_temperature( &temphum16, &temperature );
log_printf( &logger, " Temperature : %.2f C\r\n", temperature );
temphum16_get_humidity( &temphum16, &humidity );
log_printf( &logger, " 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

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. UART terminal is available in all MikroElektronika compilers.
