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.

  • Date : May 2021.
  • Type : I2C/SPI type

Software Support

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.

Library Description

This library contains API for TempHum16 Click driver.

Standard key functions :

  • 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 );

Example key functions :

  • 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 );

Example Description

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 :

Application Init

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_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );

    // Click initialization.

    temphum16_cfg_setup( &temphum16_cfg );
    TEMPHUM16_MAP_MIKROBUS( temphum16_cfg, MIKROBUS_1 );
    err_t init_flag  = temphum16_init( &temphum16, &temphum16_cfg );
    if ( ( init_flag == I2C_MASTER_ERROR ) || ( init_flag == SPI_MASTER_ERROR ) ) {
        log_info( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    temphum16_default_cfg ( &temphum16 );
    log_info( &logger, " Application Task " );
    Delay_ms ( 100 );

    temphum16_get_device_id( &temphum16, &device_id );
    log_printf( &logger, "-----------------------\r\n" );
    log_printf( &logger, "  Check communication  \r\n" ); 
    if ( device_id == TEMPHUM16_DEVICE_ID ){
        log_printf( &logger, "      Successful   \r\n" );    
    } else {
        log_printf( &logger, "        Failed     \r\n" );

        for ( ; ; );
    }

    log_printf( &logger, "-----------------------\r\n" );
    log_printf( &logger, "   Start measurements  \r\n" );
    log_printf( &logger, "-----------------------\r\n" );
}

Application Task

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.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.TempHum16

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.

LED Driver 13 Click is a compact add-on board that simplifies the control of multiple LEDs. This board features the A80604-1, a 4-channel LED driver designed at a switching frequency of 400kHz that provides 150mA per channel from Allegro Microsystems. It is powered by an external power supply in the range of 6V to 18V, providing an output voltage of approximately 26V, which is used to power LEDs connected to LED channels. On the logical side, this board uses both 3V3 and 5V with mikroBUS™ power rails and communicates with the MCU via GPIO pins. In addition, the user is given the option of analog or digital LED dimming selection, using a PWM pin from the mikroBUS™ socket or via an onboard potentiometer/external PWM signal.

MCP251863 Click is a compact add-on board representing a complete CAN solution used as a control node in a CAN network. This board features the MCP251863, IC representing a compact solution with a controller and a transceiver in one package, the MCP2518FD and ATA6563 from Microchip. The ATA6563, a low-level physical layer IC (PHY), provides a physical connection with the CAN bus itself, while the CAN controller MCP2518FD represents an interface between the MCU and the PHY. It features three operating modes with dedicated fail-safe features, remote wake-up via CAN, and ideally passive behavior when powered off on the CAN bus. This Click board™ is suitable for developing a wide range of automotive diagnostic applications, even on MCUs that don’t support CAN interface.
