As the successor to the widely adopted BMP180, the BMP280 delivers high performance in all applications that require precise pressure measurement.

Manufactured by Bosch Sensortec, the BMP280 operates at lower noise and supports new filter modes. The BMP280 also provides a temperature measurement, anywhere from 0 to 65°C.

The BMP280 is based on piezo-resistive technology for EMC robustness, high accuracy as well as long stability. The E2PROM has stored 176 bit of individual calibration data. This is used to compensate for offset, temperature dependence, and other parameters of the sensor.

Typical applications for this device include:

  • enhancement of GPS navigation (dead-reckoning, slope detection, etc.),
  • the weather forecast, and
  • vertical velocity indication (rise/sink speed).

The BMP280 is also perfectly suitable for applications like floor detection since this sensor features excellent relative accuracy which is ± 0.12 hPa or ±1 m difference in altitude.

All I2C Mini Modules are designed to operate at 5VDC. Using a convenient 4-Pin plug, devices can be daisy-chained onto the I2C Bus, eliminating the need for soldering. Simply plug together the devices you need for your next automation application.

Pull-up resistors are included with all Dcube Store master devices. If you are wiring in your own I2C port, on-board 4.7K jumper-selectable pull-up resistors are available for convenience purposes.

FREE I2C cable included.
