Hardware Overview
How does it work?
Thermo 30 Click is based on the STS32-DIS-10KS, a third-generation, high-reliability, certified digital temperature sensor from Sensirion. Every sensor has its unique serial number and is supplied with an ISO17025-accredited calibration certificate, which comprises three temperatures: −30°C, 5°C, and 70°C. The calibration is performed on each sensor and granted by the Swiss Accreditation Service. The calibration data and the serial number are stored in the onboard memory. Temperature data can be acquired both in Single Shot and Periodic Data mode as a 16-bit temperature value. The sensor is also equipped with an internal heater that can be used for plausibility checking
only and can be switched on and off through software. The Thermo 30 Click uses a standard 2-Wire I2C interface to communicate with the host MCU with fast-mode support and frequencies up to 1MHz. The I2C address can be selected via the ADDR SEL jumper (0 set by default). The STS32-DIS-10KS can be reset via the RST pin of the mikroBUS™ socket, through a general call, or software as a soft reset. Resetting over the RST pin or through a general call (according to I2C specifications) achieves a full reset, while with the soft reset, the sensor resets the system controller and reloads calibration data from memory. In addition, the Thermo 30 Click comes with an
alert function, a feature that can interrupt the host MCU over the ALR pin of the mikroBUS™ socket if there is an alarm condition. The red ALARM LED stands as a visual presentation of this feature. 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 demonstrates the use of Thermo 30 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
* starts the periodic measurements at 1 mps with high repeatability.
*
* ## Application Task
* Reads the temperature measurement in degrees Celsius and displays the results on the USB UART
* approximately once per second.
