Bosch BMP390L digital barometric pressure sensor module. It features extremely high-temperature stability, low drift, low power consumption and low noise. The maximum deviation of absolute accuracy is less than 50 Pa and the relative accuracy can be ±3 Pa (equivalent to 25 cm), which is 166.7% higher than the previous generation. The measurement range is from 300 hPa to 1250 hPa. It communicates via an I2C / SPI interface. The supply voltage is 3.3 V.

Main features:
  • High precision (absolute deviation < 50 Pa, relative accuracy < 3 Pa)
  • High long-term stability (±16 Pa/year)
  • Extremely high-temperature stability and low drift
  • Low power consumption (54 uA in sleep mode, < 650 uA during operation)
