Thermo 9 Click Board™

Product Code: MIKROE-3983

How Does The Thermo 9 Click Board™ Work? The main feature of the Thermo 9 Click Board™ is the TSYS01. This is a single device, versatile, new technology temperature sensor. The TSYS01 provides factory calibrated temperature information and it includes a temperature sensing chip and a 24-bit ΔΣ-ADC. The essence of the digital 24-bit temperature value and the internal calibration values lead to highly accurate temperature information accompanied by high measurement resolution. The TSYS01 can be interfaced to any microcontroller by an I2C or SPI interface. This microcontroller has to calculate the temperature result based on the ADC values and the calibration parameters. The TSYS01 has the SPI and the I2C Interface. When it comes to the I2C communication, it starts with a start condition and it is ended by a stop condition. Each command consists of two bytes: the address byte and command byte. The SPI communication is a 4-wire SPI bus, operating as a slave. CS (chip select), SCLK (serial clock), SDI (serial data in), and SDO (serial data out) are used to interact with the SPI master.

Communication with the chip starts when CS is pulled to low and ends when CS is pulled to high. SCLK is controlled by the SPI master and idles low (SCLK low on CS transitions, mode 0). A mode where the clock alternatively idles high is also supported (mode 3). The basic operating principles of the TSYS01 include several important features. Basically, converting temperature into digital 16/24 bit ADC value and providing calibration coefficients while also providing ADC value and calibration coefficients by SPI or I2C interface. Given the most notable features of the Thermo 9 Click Board™, it can be used for industrial control, replacement of thermistors and NTCs, heating/cooling systems, and HVAC. The design of the Click board™ itself is such that the thermal radiation from other components, which might affect the environmental temperature readings of the sensor, is reduced. The onboard SMD jumper labeled as VCC SEL allows voltage selection for interfacing with both 3.3V and 5V MCUs.
