Fermion: BMP390L Digital Barometric Pressure - module with pressure sensor

Description

Module with digital barometer BMP390L. It enables pressure measurement in the range from 300 to 1250 hPa with an accuracy of ± 3 Pa, which in relation to height gives an accuracy of 0.25 m. The system also allows temperature measurement in the range from -40℃ to 85℃. The sensor uses the piezo resistive pressure sensor technology by Bosch, which is characterized by high accuracy, low energy consumption and high resistance to electromagnetic interference, which makes it ideal for industrial applications. For communication, the module uses the I2C or SPI interface and is supplied with the voltage from 3.3 V. On the Wiki page of the product, the user manual and sample programs are available.
