Status:
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. This Click board™ is suitable for the thermal management of various consumer, industrial, and environmental applications.
Thermo 26 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.

Availability date:
Thermo 26 Click is based on the STS31-DIS, a digital temperature sensor from Sensirion with increased intelligence, reliability, NIST traceability, and improved accuracy specifications utilizing the industry-proven CMOSens® Technology. It integrates a digital temperature sensor with a 16-bit analog-to-digital converter (ADC), a data processing circuit, and serial interface logic functions in one package. The voltage is digitized and converted to a 16-bit temperature result in degrees Celsius, with a resolution of 0.01°C.
The STS31-DIS temperature sensor gives a fully calibrated, linearized, and supply-voltage-compensated digital output with outstanding accuracy of up to ±0.2°C typical over a temperature range of 0°C to 90°C.
Thermo 26 Click communicates with an MCU using the standard I2C 2-Wire interface to read data and configure settings, supporting Fast Mode Plus up to 1MHz. Also, the STS31-DIS allows choosing the least significant bit (LSB) of its I2C slave address using the SMD jumper labeled ADDR SEL. It also possesses an additional interrupt alert signal, routed on the INT pin of the mikroBUS™ socket labeled as ALT, indicating when a specific interrupt event occurs that depends on the value of the temperature reading relative to programmable limits and general reset function routed on the RST pin of the mikroBUS™ socket.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.

We provide a library for the Thermo 26 Click as well as a demo application (example), developed using MIKROE compilers. The demo can run on all the main MIKROE development boards.
The package can be downloaded/installed directly from NECTO Studio Package Manager (recommended), downloaded from our LibStock™ or found on MIKROE github account.
Library Description
This library contains API for Thermo 26 Click driver.
Key functions
thermo26_read_serial_num
This function reads the 32-bit unique serial number.
thermo26_start_measurement
This function starts the measurements by sending the specified command.
thermo26_read_temperature
This function reads the temperature raw data measurements and converts them to degrees Celsius.
Example Description
This example demonstrates the use of Thermo 26 Click board™ by reading and displaying the temperature measurements.
void application_task ( void )
{
float temperature;
if ( THERMO26_OK == thermo26_read_temperature ( &thermo26, &temperature ) )
{
log_printf ( &logger, " Temperature: %.2frnn", temperature );
}
Delay_ms ( 1000 );
}
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager (recommended), 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 a 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. A UART terminal is available with all MIKROE compilers.
This Click board™ is supported with mikroSDK – MIKROE’s Software Development Kit. mikroSDK should be downloaded from the LibStock™ and installed for the compiler you are using to ensure proper operation of mikroSDK compliant Click board™ demo applications.
For more information about mikroSDK, visit the official page.
NOTE: Please be advised that any peripheral devices or accessories shown connected to the Click board™ are not included in the package. Check their availability in our shop or in the YMAN section below.
