Description

Module with digital barometer BMP388. The system enables pressure measurement in the range from 300 to 1250 hPa with an accuracy of ± 8 Pa, which in relation to height gives an accuracy of 0.5 m. It also enables temperature measurement in the range from -40 ℃ to 80 ℃. The BMP388 uses Bosch's piezo resistive pressure sensor technology, with high accuracy, low power consumption and high resistance to electromagnetic interference. The module uses the I2C or SPI interface for communication. It is supplied with the voltage from 3.3 V to 5 V. On the Wiki page of the product, the user manual and sample Arduino programs are available.
