The HTU21D-F is an I²C digital temperature and humidity sensor with high accuracy and an operating range that is optimised from 5 to 95% RH and from -30°C to +90°C. The breakout board includes a PTFE filter to keep the sensor clean, a 3.3V regulator and I⊃2C level shifting circuitry. This allows the board to be used safely with any kind of microcontroller with 3.3 to 5V power or logic.
The BN0055 is a nine degrees of freedom (9-DOF) sensor that fuses and processes the plethora of data associated with a 9-DOF sensor. The board can output the vectors of absolute orientation (Quaternion and Euler vector), angular velocity, acceleration, magnetic field strength, linear acceleration, gravity, and temperature. The data can be read over an I²C interface.
