Thermo 30 Click Board™

Product Code: MIKROE-5736

How Does The Thermo 30 Click Board™ Work? The Thermo 30 Click Board™ 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 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. In contrast, 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. The Thermo 30 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.
