Product Code: SEN05291P


This Grove Barometer Sensor features a Bosch BMP085 high-accuracy chip to detect barometric pressure and temperature. The sensor has a wide pressure range--from 300hPa to 1100hPa, or approximately +9000m to -500m below sea level, with a super high accuracy of 0.03hPa(0.25m) in ultra-high resolution mode.

The chip only accepts 1.8V to 3.6V input voltage. However, a circuit has been added to enable this module to be compatible with 3.3V and 5V logic, so it can be used on Arduino/Seeeduino or Seeeduino Stalker without modification. Since it's a Grove device, it's just plug and play!

  • Wide pressure range
  • Grove-compatible interface (3.3V or 5V)
  • I2C interface
  • Fully calibrated
  • Low power consumption: 5μA at 1 sample/sec. in standard mode
  • Low noise:
    1. 0.06hPa (0.5m) in ultra-low power mode
    2. 0.03hPa (0.25m) in ultra-high resolution mode
    3. Possibility to lower to 0.1m (rms noise)
Application Ideas:
  • Enhancement of GPS navigation
  • Indoor and outdoor navigation
  • Leisure and sports
  • Weather forecast
  • Vertical velocity indication (rise/sink speed)
