Thermo 26 click

Thermo 26 Click is a compact add-on board that accurately measures temperature. This board features the STS31-DIS, a high-accuracy digital temperature sensor from Sensirion. Characterized by its high accuracy (up to ±0.2°C typical) and high resolution of 0.01°C, the STS31-DIS provides temperature data to the host controller with a configurable I2C interface. It relies on the industry-proven CMOSens® technology, providing increased intelligence, reliability, and improved accuracy specifications, including enhanced signal processing, user-selectable I2C addresses, and up to 1 MHz communication speeds.

Software Support

We provide a library for the Thermo 26 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 Thermo 26 Click driver.

Standard key functions :

Example Description

This example demonstrates the use of Thermo 26 click board by reading and displaying the temperature measurements.

The demo application is composed of two sections :

Application Init

Initializes the driver and resets the device, and after that reads the serial number and starts the periodic measurements at 2 mps with high repeatability.

void application_init ( void )
{
log_cfg_t log_cfg;
thermo26_cfg_t thermo26_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
thermo26_cfg_setup( &thermo26_cfg );
THERMO26_MAP_MIKROBUS( thermo26_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == thermo26_init( &thermo26, &thermo26_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
thermo26_reset_device ( &thermo26 );
uint32_t serial_num;
if ( THERMO26_ERROR == thermo26_read_serial_num ( &thermo26, &serial_num ) )
{
log_error( &logger, " Read serial number." );
for ( ; ; );
}
log_printf ( &logger, " Serial number: 0x%.8LX\r\n", serial_num );
{
log_error( &logger, " Start measurement." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

Reads the temperature measurement in degrees Celsius and displays the results on the USB UART approximately once per second.

void application_task ( void )
{
float temperature;
if ( THERMO26_OK == thermo26_read_temperature ( &thermo26, &temperature ) )
{
log_printf ( &logger, " Temperature: %.2f\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.Thermo26

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.
