Hardware Overview
How does it work?
Thermo 20 Click is based on the TSYS03, an ultra-compact digital temperature sensor with precise digital output and low power consumption from TE Connectivity. The TSYS03 is factory-calibrated and provides accurate temperature measurements through several I2C configurable addresses. Operating from a supply voltage between 2.4V and 5.5V and drawing just 5µA 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 that offer an 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, 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 temporary and is overwritten during a software reset or a hardware restart function. 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. Also, this 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.
Features overview
Development board
Nucleo 32 with STM32F031K6 MCU board provides an affordable and flexible platform for experimenting with STM32 microcontrollers in 32-pin packages. Featuring Arduino™ Nano connectivity, it allows easy expansion with specialized shields, while being mbed-enabled for seamless integration with online resources. The
board includes an on-board ST-LINK/V2-1 debugger/programmer, supporting USB reenumeration with three interfaces: Virtual Com port, mass storage, and debug port. It offers a flexible power supply through either USB VBUS or an external source. Additionally, it includes three LEDs (LD1 for USB communication, LD2 for power,
and LD3 as a user LED) and a reset push button. The STM32 Nucleo-32 board is supported by various Integrated Development Environments (IDEs) such as IAR™, Keil®, and GCC-based IDEs like AC6 SW4STM32, making it a versatile tool for developers.

*
* # Description
* This example showcases the ability of Thermo 20 Click board to
* read it's serial number. It can read themperature and measure from -40degC to
* 120degC.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initialization communication modules(I2C, UART). Resets device and read Serial Number.
*
* ## Application Task
* In span of ~ 1000ms it sends command for adc conversion of temperature, reads ADC value,
* and calculates temperature in degrees C.
*
* @note For this driver to work on 18bit PIC MCU-s you need to additionally pull up communication lines.
