Thermo 20 Click Board™

Product Code: MIKROE-4316

How Does The Thermo Click 20 Board Work? The Thermo 20 Click Board™ is based on the TSYS03, an ultra-compact digital temperature sensor with precise digital output and low power consumption from TE Connectivity Measurement Specialties. The TSYS03 is factory calibrated and provides accurate temperature measurements through several I2C configurable addresses. Operating from a supply voltage ranging between 2.4V and 5.5V and drawing just 5µA. The Thermo 20 Click board™ is well suited for battery-powered and automotive applications. With an extended operating range from -40°C to +125°C, the TSYS03 provides digital temperature measurements which offer accuracy of ±0.5°C when operating at ambient temperatures between 0°C and 60°C. The TSYS03 consists of a semiconductor diode as a measuring element, which was integrated into an ASIC. The temperature is obtained from the voltage that drops across the diode, and through an A/D converter with a 16-bit resolution, the output is obtained as a digital value via a configurable I2C interface.

The TSYS03 impresses with its high accuracy, the current consumption lower than 5 µA, and low self-heating of max. 0.1 °C. Thermo 20 Click communicates with MCU using the standard I2C 2-Wire interface with a maximum clock frequency of 1MHz. The standard I2C address is 0x40, but the sensor can also react to a second, alternative I2C address. It is possible to do one-time subsequent writing of an alternative static I2C address. This leads to a wrong memory CRC, but the sensor is still functional. It is also possible to write an alternative I2C address to the sensor during operation. This address is temporally and is overwritten during a software reset or a hardware restart function. The Thermo 20 Click board™ logic voltage levels that can be selected via VCC SEL jumper. This allows for both 3.3V and 5V capable MCUs to use the I2C 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. SPECIFICATIONS Type Temperature & humidity Applications Can be used for industrial control, as a replacement of precision RTDs, thermistors, and NTCs, or in any other temperature measurement applications.
