About this item

  • BMP388 indludes a new FIFO functionality. This greatly improves ease of use while helping to reduce power consumption of the overall device system during full operation. The integrated 512 byte FIFO buffer supports low power applications and prevents data loss in non-real-time systems.
  • The sensor is more accurate than its predecessor BMP280, covering a wide measurement range from 300 hPa to 1250 hPa. This new barometric pressure sensor exhibits an attractive price -performance ratio coupled with low power consumption.
  • Due to the built-in hardware synchronization of the pressure sensor data and its ability to synchronize data from extermal
  • The new interrupt functionality provides simple access to data and storage. Examples of interrupts than can be used in a power efficient manner without using software algorithms include: Data ready interrupt, watermark interrupt (on byte level) or FIFO full interrupt.
  • Suitable for Vertical velocity indication, Internet of things, Enhancement of GPS navigation, Indoor navigation & localization, Outdoor navigation, leisure and sports applications, Health care applications, Fitness applications like enhancement of calorie detection, AR & VR applications, Context awareness

These sensors are pretty neat and works as well as the one from adafruit with only half the cost. I've ran some test on the accuracy and the error is within 2%. It is well worth the price and good enough for any hobbyist application.
