Description

  • DFRobot Gravity BMP388 Barometric Pressure Sensors
  • Low power consumption
  • Low noise & High resolution
  • Offset temperature coefficient (-20℃-65℃@700-1100hPa)

The DFRobot Gravity BMP388 Barometric Pressure Sensors is equipped with the functionality of temperature and pressure measurement. It supports Arduino code control.

BMP388 is based on Bosch’s mature Piezo resistive pressure sensor technology featuring high accuracy as well low power consumption and high EMC robustness.

The sensor features an accuracy of about ±8Pa, which is equivalent to about ±0.5m difference in altitude, and an absolute accuracy temperature of ±0.5 ℃ for a temperature range between 0 and 65 ℃.
