MIKROE Pressure 17 Click

Product Overview

Pressure 17 Click is a compact add-on board that contains a board-mount pressure sensor. This board features the BM1390GLV-Z, a high-precision piezoresistive pressure sensor from Rohm Semiconductor. The BM1390GLV-Z comes with a configurable host interface that supports I2C serial communication and measures pressure in a range from 300hPa up to 1300hPa with an accuracy of ±1hPa. It also has a built-in temperature compensation function that internally performs temperature compensation for MEMS inside the chip, so it’s easy to get pressure information, built-in FIFO, and operation in a temperature range of -40°C to 85°C, which ensures stable operation under extreme conditions. This Click board™ is suitable for pressure measurements in automotive applications, industrial and consumer applications.

Pressure 17 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.

Pressure 17 Click as its foundation uses the BM1390GLV-Z, ultra-compact piezoresistive pressure sensor from Rohm Semiconductor. This MEMS-based absolute pressure sensor includes a sensing element, analog to digital converter, signal processing part, and digital interface that sends the digital pressure data to the host controller. The MEMS-based sensing element measures pressure in a range from 300hPa up to 1300hPa with an accuracy of ±1hPa over a wide operating temperature range at the industry’s lowest power.

It also has a built-in temperature compensation function that internally performs temperature compensation for MEMS inside the chip, so it’s easy to get pressure information, built-in FIFO, and operation in a temperature range of -40°C to 85°C, which ensures stable operation under extreme conditions.

Pressure 17 Click communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings, supporting Standard Mode operation with a clock frequency of 100kHz and Fast Mode up to 400kHz. It also possesses an additional interrupt signal, routed on the INT pin of the mikroBUS™ socket labeled as INT, indicating when a specific interrupt event occurs.

This 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.
