How Does The Barometer 10 Click Board™ Work?
The Barometer 10 Click Board™ is based on the LPS28DFW, a high-accuracy absolute pressure sensor that functions as a digital output barometer from STMicroelectronics. The LPS28DFW delivers ultra-low pressure noise with low power consumption and operates over an extended temperature range. It has a selectable dual full-scale absolute pressure range, from 260 up to 1260hPa or 4060hPa, with an absolute pressure accuracy of 0.5hPa, ideally suited to the harsh environmental conditions in industrial and consumer applications.
The LPS28DFW has a unique cylindrical package solution with a full metal lid assembled on a ceramic substrate. This cylindrical package provides the easy assembly with O-rings in the end user's application. Its sensing element is based on a piezoresistive Wheatstone bridge approach with an interface that provides a digital signal from the sensing element to the application. The sensing element, which detects absolute pressure, consists of a silicon membrane manufactured using a dedicated process developed by ST. When pressure is applied, the membrane deflection induces an imbalance in the Wheatstone bridge piezoresistance, whose output signal is converted by the serial interface into a 24-bit output pressure data.
The trimming values are stored inside the LPS28DFW in a non-volatile structure. When the LPS28DFW is turned on, the trimming parameters are downloaded into the registers to be employed during normal operation, allowing the device to be used without further calibration.
This Click board™ communicates with an MCU using the standard I2C 2-Wire interface to read data and configure settings, supporting Fast-Plus mode with a frequency of up to 1MHz. In addition, the LPS28DFW allows choosing the least significant bits (LSB) of its I2C slave address using the SMD jumper labelled ADDR SEL. The LPS28DFW features a data-ready signal, routed on the INT pin of the mikroBUS™ socket, which indicates when a new set of measured pressure and temperature data are available, thus simplifying data synchronization in the digital system that uses the device.
The Barometer 10 Click Board™ can only be operated 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.
