Altitude 6 Click Board™

Product Code: MIKROE-4903

How Does The Altitude 6 Click Board™ Work? The Altitude 6 Click Board™ as its foundation uses the MS5611-01BA03-50, a high-resolution barometric pressure sensor optimized for altimeter applications with an altitude resolution of 10 cm from TE Connectivity. The MS5611-01BA03-50 consists of a piezo-resistive sensor with an integrated signal conditioning circuit that can measure pressure in a range from 10 mbar up to 1.2bar with an accuracy of 1.5 mbar over a wide operating temperature range at the lowest power consumption. The high accuracy and stability of both pressure and temperature signal make it suitable for height sensing in medical and consumer applications, mobile altimeter or barometer systems, and many more. The MS5611-01BA03-50 also has ultra-low-power 24-bit ΔΣ ADC with internal factory calibrated coefficients along with a high linearity pressure sensor. Its primary function is to convert the uncompensated analog output voltage from the piezo-resistive pressure sensor to a 24-bit digital value and provide a 24-bit digital value for the sensor's temperature, which allows the implementation of an altimeter function without any additional sensor.

The Altitude 6 Click Board™ allows using both I2C and SPI interfaces with a maximum frequency of 20MHz. The selection can be made by positioning SMD jumpers labeled as COMM SEL to an appropriate position. Note that all the jumpers' positions must be on the same side, or the Click board™ may become unresponsive. While the I2C interface is selected, the MS5611-01BA03 allows choosing the least significant bit (LSB) of its I2C slave address using the SMD jumper labeled as ADDR SEL to an appropriate position marked as 0 and 1. The Altitude 6 Click Board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before use with MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
