Das Thermo 20 Click Board™ ist eine kompakte Zusatzplatine, die eine genaue Temperaturmessung ermöglicht. Diese Platine verfügt über den TSYS03, einen digitalen Miniaturtemperatursensor, der werkseitig kalibrierte, hochgenaue Temperaturdaten von TE Connectivity Measurement Specialties liefert. Dieser Temperatursensor zeichnet sich durch seine Genauigkeit und hohe Auflösung aus und bietet einen digitalen Ausgang mit einer konfigurierbaren I2C-Schnittstelle, sorgt für kürzere Konvertierungszeit mit präziser Temperaturmessung und bietet einen Sensor mit geringem Stromverbrauch, der für batteriebetriebene Anwendungen geeignet ist. Dieses Click Board™ eignet sich für die industrielle Steuerung, als Ersatz für Präzisions-RTDs, Thermistoren und NTCs oder für andere Temperaturmessanwendungen.
Das Thermo 20 Click Board™ wird von einer mikroSDK-kompatiblen Bibliothek unterstützt, die Funktionen enthält, die die Softwareentwicklung vereinfachen. Dieses Click Board™ wird als vollständig getestetes Produkt geliefert und ist bereit für den Einsatz auf einem System, das mit der mikroBUS™-Buchse ausgestattet ist.
How Does The Thermo Click 20 Board Work?
The Thermo 20 Click Board™ is based on the TSYS03, an ultra-compact digital temperature sensor with precise digital output and low power consumption from TE Connectivity Measurement Specialties. The TSYS03 is factory calibrated and provides accurate temperature measurements through several I2C configurable addresses. Operating from a supply voltage ranging between 2.4V and 5.5V and drawing just 5µA.
The Thermo 20 Click board™ is well suited for battery-powered and automotive applications. With an extended operating range from -40°C to +125°C, the TSYS03 provides digital temperature measurements which offer accuracy of ±0.5°C when operating at ambient temperatures between 0°C and 60°C.
The TSYS03 consists of a semiconductor diode as a measuring element, which was integrated into an ASIC. The temperature is obtained from the voltage that drops across the diode, and through an A/D converter with a 16-bit resolution, the output is obtained as a digital value via a configurable I2C interface. The TSYS03 impresses with its high accuracy, the current consumption lower than 5 µA, and low self-heating of max. 0.1 °C.
Thermo 20 Click communicates with MCU using the standard I2C 2-Wire interface with a maximum clock frequency of 1MHz. The standard I2C address is 0x40, but the sensor can also react to a second, alternative I2C address. It is possible to do one-time subsequent writing of an alternative static I2C address. This leads to a wrong memory CRC, but the sensor is still functional. It is also possible to write an alternative I2C address to the sensor during operation. This address is temporally and is overwritten during a software reset or a hardware restart function.
The Thermo 20 Click board™ logic voltage levels that can be selected via VCC SEL jumper. This allows for both 3.3V and 5V capable MCUs to use the I2C communication lines properly. However, the Click board™ comes equipped with a library that contains easy to use functions and an example code that can be used as a reference for further development.

Software Support
We provide a library for the Thermo 20 Click board™ on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Library Description
The library covers all the necessary functions to control Thermo 20 Click board™. Library performs a standard I2C interface communication.
Key Functions
float thermo20_get_temperature ( void )- Get temperature data function.void thermo20_soft_reset ( void )- Soft reset function.void thermo20_start_conversion ( void )- Start conversion function.
Example Description
The application is composed of three sections :
- System Initialization - Initializes I2C and start to write log.
- Application Initialization - Initialization driver enables - I2C, software reset the device and read the serial number, also write log.
- Application Task - (code snippet) This is an example that demonstrates the use of the Thermo 20 Click board™. Thermo 20 Click board™ can be used to measure temperature. All data logs write on USB UART changes every 3 sec.
void application_task ( ) { thermo20_start_conversion( ); Delay_ms( 100 ); temperature = thermo20_get_temperature( ); FloatToStr( temperature, log_text ); mikrobus_logWrite( " Temperature : ", _LOG_TEXT ); mikrobus_logWrite( log_text, _LOG_TEXT ); mikrobus_logWrite( " C", _LOG_LINE ); mikrobus_logWrite( "-----------------------------", _LOG_LINE ); Delay_ms( 3000 ); }
The full application code, and ready to use projects can be found on our LibStock page.
Other mikroE Libraries used in the example:
- I2C
- UART
- Conversions
Additional Notes and Information
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. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
MIKROSDK
The Thermo 20 Click board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
