Temp&Hum 15 Click

Temp&Hum 15 Click is a compact add-on board that contains the 4th generation of best-in-class SHT humidity sensing solution from Sensirion. This board features the SHT40, a high-accuracy ultra-low-power 16-bit relative humidity, and temperature sensor.

Click library

  • Author : Stefan Nikolic
  • Date : jan 2021.
  • Type : I2C type

Software Support

We provide a library for the TempHum15 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 TempHum15 Click driver.

Standard key functions :

  • temphum15_cfg_setup Config Object Initialization function.

    void temphum15_cfg_setup ( temphum15_cfg_t *cfg );
  • temphum15_init Initialization function.

    TEMPHUM15_RETVAL temphum15_init ( temphum15_t *ctx, temphum15_cfg_t *cfg );
  • temphum15_default_cfg Click Default Configuration function.

    void temphum15_default_cfg ( temphum15_t *ctx );

Example key functions :

  • temphum15_get_temp_and_hum This function reads temperature and humidity with the power consumption based on the precision mode selected.

    err_t temphum15_get_temp_and_hum ( temphum15_t *ctx, uint8_t precision_mode, float *temp_val, float *hum_val );
  • temphum15_soft_reset This function sends soft reset command to the sensor.

    err_t temphum15_soft_reset ( temphum15_t *ctx );
  • temphum15_read_serial This function reads unique serial number of the sensor.

    err_t temphum15_read_serial ( temphum15_t *ctx, uint32_t *serial_number );

Example Description

This demo app represents the performance of the Temp&Hum 15 Click board. The log displays the temperature and humidity obtained from the sensor.

The demo application is composed of two sections :

Application Init

Initialization of UART LOG and I2C drivers. The application also performs reset upon init.


void application_init ( void ) {
    log_cfg_t log_cfg;              /**< Logger config object. */
    temphum15_cfg_t temphum15_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.

    temphum15_cfg_setup( &temphum15_cfg );
    TEMPHUM15_MAP_MIKROBUS( temphum15_cfg, MIKROBUS_1 );
    err_t init_flag = temphum15_init( &temphum15, &temphum15_cfg );
    if ( init_flag == I2C_MASTER_ERROR ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    Delay_ms ( 100 );
    temphum15_default_cfg( &temphum15 );
    log_info( &logger, " Application Task " );
    Delay_ms ( 100 );
}

Application Task

Temperature and humidity data are being acquired every two seconds. If the acquisition fails, LOG states that no data is available.


void application_task ( void ) {
    err_t status_data;

    status_data = temphum15_get_temp_and_hum( &temphum15, TEMPHUM15_MODE_HIGH_PRECISION, &temperature, &humidity );
    if ( status_data == TEMPHUM15_SUCCESS ) {
        log_printf( &logger, "----------------------------\r\n" );
        log_printf( &logger, "> Temperature : %.2f C\r\n", temperature );
        log_printf( &logger, "> Humidity: %.2f %RH\r\n", humidity );
    } else {
        log_printf( &logger, "----------------------------\r\n" );
        log_printf( &logger, "> No data\r\n" );
    }
    Delay_ms ( 1000 );
    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.TempHum15

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.

1-Wire I2C click

10

1-Wire I2C click converts the 1-wire signal from the MCU to I2C signal, which is then sent to the slave, and vice versa. The click carries DS28E17 1-Wire-to-I2C master bridge from Maxim Integrated. 1-Wire I2C click runs on a 3.3V power supply.
