    MIKROE Thermo 18 Click is a compact add-on board that provides an accurate temperature measurement. This board features the WSEN-TIDS, a silicon-based, high-precision digital temperature sensor with embedded analog and digital signal processing unit from Würth Elektronik. This temperature sensor, characterized by its high accuracy (up to ±0.25 °C typical) and high resolution, provides factory-calibrated 16-bit temperature data to the host controller with a configurable I2C interface. It also comes with a programmable temperature threshold and an interrupt feature. This Click board™ is appropriate for industrial control, environmental monitoring, domestic appliances, HVAC systems, or other temperature measurement applications.

    Thermo 18 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.

    Thermo 18 Click as its foundation uses the WSEN-TIDS (2521020222501), a silicon-based, high-resolution digital temperature sensor from Würth Elektronik. This temperature sensor is characterized by high accuracy; temperature range of -40°C to +125°C provides ±0.5°C accuracy, while a range of -10°C to +60°C it goes down to ±0.25°C. WSEN-TIDS sensor is factory-calibrated and can be used without time-consuming re-measurements. It features a 16-bit output signal that can be read out via an I2C serial interface with output data rates up to a maximum of 200Hz.

    This Click board™ can be configured in the three following operational modes: Power-down mode, Single conversion mode, and Continuous mode. In Power-down mode, the digital chain that samples the temperature data is turned off, and the current consumption is at its minimum. Before going into this mode, the temperature data registers retain the last sampled temperature value. However, serial communication with the host controller via the I2C bus is still possible, allowing the user to configure the device by accessing the control registers and temperature threshold registers.

    The Single conversion mode can activate when the sensor is still in a Power-down mode allowing a single temperature measurement to be performed according to the request of the host controller, while the continuous mode constantly samples new temperature measurements and writes the data to the temperature data registers. Once the device is configured in one of the operating modes, temperature values are sampled and stored in the temperature data registers, available for the user to read.

    Thermo 18 Click communicates with MCU using the standard I2C 2-Wire interface with a frequency of 400kHz in Fast Mode and up to 1MHz in Fast Mode Plus. Also, the WSEN-TIDS features an interrupt signal routed on the INT pin of the mikroBUS™ socket, which indicates when a new set of measured temperature data are available, simplifying data synchronization in the digital system that uses the device. Besides, it also allows the choice of the least significant bit of its I2C peripheral address by positioning the SMD jumper labeled as ADDR SEL to an appropriate position marked as 0 and 1.

    This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before use with MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
