    MIKROE Thermo 21 Click is a compact add-on board that provides an accurate temperature measurement. This board features the ADT7301, a high-precision digital temperature sensor from Analog Devices. The ADT7301 houses an on-chip temperature sensor, a 13-bit A/D converter, a reference circuit, and serial interface logic functions in one package. Characterized by its high accuracy (up to ±0.5°C typical) and high resolution of 0.03125°C, this temperature sensor provides temperature data to the host controller with a configurable SPI interface. This Click board™ is appropriate for process control, environmental monitoring, domestic appliances, electronic test equipment, or other temperature measurement applications.

    Thermo 21 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.

    Thermo 21 Click as its foundation uses the ADT7301, a high-precision digital temperature sensor from Analog Devices. This temperature sensor is characterized by high accuracy; temperature range of 0°C to +70°C provides typical ±0.5°C accuracy. It contains a band-gap temperature sensor and a 13-bit ADC to monitor and digitize the temperature reading to a resolution of 0.03125°C. Wide supply voltage range, low supply current, and SPI-compatible interface make it ideal for various applications, including process control, environmental monitoring, domestic appliances, and many more.

    The ADT7301 is a 13-bit digital sensor with a 14th bit that acts as a sign bit. The internal ADC section of the ADT7301 consists of a conventional successive approximation converter based around a capacitor DAC. The on-chip temperature sensor allows an accurate measurement of the ambient device temperature, where the specified measurement range is −40°C to +150°C. It is unrecommended to operate the device at temperatures above +120°C because exposure beyond this limit affects device reliability.

    This Click board™ communicates with MCU through a standard SPI interface to program the internal registers for complete control of the ADT7301. It is compatible with SPI, QSPI, and MICROWIRE protocols as well as DSPs. The ADT7301 can be placed into Shutdown mode via the control register, which means that the on-chip oscillator is shut down, and no further conversions are initiated until the ADT7301 is taken out of Shutdown mode.

    This Click board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the SPI 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.
