HOW DOES IT WORK?
Thermo 24 Click as its foundation uses the STS40, a high-accuracy ultra-low-power 16-bit temperature sensor from Sensirion. This temperature sensor is characterized by high accuracy; temperature range of -40°C to +120°C provides typical ±0.2°C accuracy. 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 STS40 achieves the most significant cost efficiency among comparable sensors.
The STS40 communicates with MCU using a standard I2C 2-Wire interface. Given that this chip can be found in multiple versions with its own unique I2C slave address, this version, specifically the STS40-AD1B, comes with the slave address of 0x44. Since the sensor for operation requires a 3.3V logic voltage level only, this Click board™ also features the PCA9306 voltage-level translator from Texas Instruments. The I2C interface bus lines are routed to the dual bidirectional voltage-level translator, allowing this Click board™ to work with both 3.3V and 5V MCUs properly.
This Click board™ can operate with both 3.3V and 5V logic voltage levels selected via the VIO SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the communication lines properly. However, the Click board™ comes equipped with a library that contains easy-to-use functions and an example code that can be used, as a reference, for further development.
