IR Sense 5 Click

IR Sense 5 Click is a compact add-on board designed for accurate, non-contact surface temperature measurement. This board features the ZTP-148SRC1, a thermopile IR sensor from Amphenol, with a measurement range from -20 to +100°C, an active area of 0.7x0.7mm², and a typical field of view of 85 degrees. The board also integrates an OPA2365AIDR OpAmp for signal amplification and an MCP3221 analog-to-digital converter for digitizing the output. Additional features include output offset selection and test points for signal monitoring.

• Date : Feb 2024.
• Type : ADC/I2C type

Software Support

We provide a library for the IR Sense 5 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 IR Sense 5 Click driver.

Standard key functions :

• irsense5_cfg_setup Config Object Initialization function.

  void irsense5_cfg_setup ( irsense5_cfg_t *cfg );

• irsense5_init Initialization function.

  err_t irsense5_init ( irsense5_t *ctx, irsense5_cfg_t *cfg );

Example key functions :

• irsense5_get_obj_temp This function reads and calculate object temperature in degree Celsius [degC].

  err_t irsense5_get_obj_temp ( irsense5_t *ctx, float *obj_temp );

• irsense5_get_amb_temp This function reads and calculate ambient temperature in degree Celsius [degC].

  err_t irsense5_get_amb_temp ( irsense5_t *ctx, float *amb_temp );

• irsense5_read_raw_adc_thm This function reads the thermistor raw ADC value.

  err_t irsense5_read_raw_adc_thm ( irsense5_t *ctx, uint16_t *raw_adc );

Example Description

This library contains API for the IR Sense 5 Click driver for measuring ambient and object temperature.

The demo application is composed of two sections :

Application Init

The initialization of the I2C and ADC module and log UART.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    irsense5_cfg_t irsense5_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.
    irsense5_cfg_setup( &irsense5_cfg );
    IRSENSE5_MAP_MIKROBUS( irsense5_cfg, MIKROBUS_1 );
    err_t init_flag = irsense5_init( &irsense5, &irsense5_cfg );
    if ( ( ADC_ERROR == init_flag ) || ( I2C_MASTER_ERROR == init_flag ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
}

Application Task

The demo application measures ambient and object temperature in degrees Celsius. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void ) 
{
    float temperature = 0;
    if ( IRSENSE5_OK == irsense5_get_amb_temp ( &irsense5, &temperature ) )
    {
        log_printf( &logger, " Ambient Temperature: %.2f [degC]\r\n", temperature );
        Delay_ms ( 1000 );
    }

    if ( IRSENSE5_OK == irsense5_get_obj_temp ( &irsense5, &temperature ) )
    {
        log_printf( &logger, " Object Temperature:  %.2f [degC]\r\n\n", temperature );
        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.IRSense5

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.
