The Pressure 21 Click Board™ is a compact add-on board that contains a board-mount pressure sensor. This board features the BMP581, an absolute barometric pressure sensor from Bosch Sensortec. The BMP581 provides a relative accuracy of ±6Pa and typical absolute accuracy of ±30Pa with ultra-low noise, low power consumption, and temperature stability alongside programmable output: temperature-only or both pressure and temperature (pressure-only is not supported). It converts output data into a 24-bit digital value and sends the information via a configurable host interface that supports SPI and I2C serial communications. It measures pressure from 30kPa up to 125kPa over a wide operating temperature range. This Click board™ is suited for various pressure-based applications, industrial, consumer, weather stations, and more.
The Pressure 21 Click Board™ is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a thoroughly tested product, ready to be used on a system equipped with the mikroBUS™ socket.
