The Altitude 2 Click Board™ is a high-resolution barometric pressure sensor board. It provides very accurate measurements of temperature and atmospheric pressure, which can be used to calculate the altitude with a very high resolution of 20cm per step. Besides that, the device also includes features such as the ultra-low noise delta-sigma 24-bit ADC, low power consumption, fast conversion times, pre-programmed unique compensation values, and more.
The low count of external components requirement, along with the simple interface which requires no extensive configuration programming, makes this sensor very attractive for building altitude or air pressure measuring applications.
