Mikroe Thermo 21 Click implements the ADT7301 temperature sensor and provides an accurate temperature measurement. The Analog Devices ADT7301 high-precision digital temperature sensor houses an on-chip temperature sensor, a 13-bit A/D converter, a reference circuit, and serial interface logic functions in a SOT-23 package. The Thermo 21 Click is characterized by its high accuracy (up to ±0.5°C typical) and high resolution of 0.03125°C. The device utilizes a configurable SPI interface to transfer temperature data to the host controller. The Mikroe Thermo 21 Click is suitable for process control, environmental monitoring, domestic appliances, electronic test equipment, or other temperature measurement applications.
