Thermo 18 Click Board™

Product Code: MIKROE-4829

How Does The Thermo 18 Click Board™ Work? The Thermo 18 Click Board™ 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. The Thermo 18 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. The Thermo 18 Click Board™ 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 slave 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.
