Thermo 26 Click is based on the STS31-DIS, a digital temperature sensor from Sensirion with increased intelligence, reliability, NIST traceability, and improved accuracy specifications utilizing the industry-proven CMOSens® Technology. It integrates a digital temperature sensor with a 16-bit analog-to-digital converter (ADC), a data processing circuit, and serial interface logic functions in one package. The voltage is digitized and converted to a 16-bit temperature result in degrees Celsius, with a resolution of 0.01°C.

The STS31-DIS temperature sensor gives a fully calibrated, linearized, and supply-voltage-compensated digital output with outstanding accuracy of up to ±0.2°C typical over a temperature range of 0°C to 90°C.

Thermo 26 Click communicates with an MCU using the standard I2C 2-Wire interface to read data and configure settings, supporting Fast Mode Plus up to 1MHz. Also, the STS31-DIS allows choosing the least significant bit (LSB) of its I2C slave address using the SMD jumper labeled ADDR SEL. It also possesses an additional interrupt alert signal, routed on the INT pin of the mikroBUS™ socket labeled as ALT, indicating when a specific interrupt event occurs that depends on the value of the temperature reading relative to programmable limits and general reset function routed on the RST pin of the mikroBUS™ socket.

This Click board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. Therefore, both 3.3V and 5V MCUs can use the communication lines. 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.
