Barometer 6 Click Board™

Product Code: MIKROE-4978

How Does The Barometer 6 Click Board™ Work? The Barometer 6 Click Board™ as its foundation uses the 2SMPB-02E, a high-accuracy digital barometric air pressure sensor from Omron Electronics, to measure air pressure in a specific environment. The sensor has a calibration parameter for broader pressure and temperature range. It measures pressure from 30kPa up to 110kPa with an accuracy of ±50Pa over a wide operating temperature range, ideally suited to the harsh environmental conditions prevalent in industrial and consumer applications. The 2SMPB-02E features a MEMS chip for sensing air pressure with high accuracy based on the built-in low noise 24-bit ADC. Individual calibration parameters are stored in One Time Programmable-ROM (OTP) and are retained when the system is powered down. An integrated temperature compensation circuit helps ensure accurate absolute pressure measurements. The Barometer 6 Click Board™ allows using both I2C and SPI interfaces with a maximum frequency of 3.4MHz for I2C and 10MHz for SPI communication.

The selection can be made by positioning SMD jumpers labelled 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 2SMPB-02E allows choosing the least significant bit (LSB) of its I2C slave address using the SMD jumper labelled ADDR SEL. This Click board™ also possesses an additional reset pin, routed to the RST pin on the mikroBUS™ socket used to implement the standard reset function. The Barometer 6 Click Board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using 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.
