Product description: Digital atmospheric pressure sensor - barometer - BMP280 - I2C - DFRobot SEN0372
Digitalatmosphericpressure sensor manufactured by DFRobot. It has an integratedBMP280chip from Bosch. The module integratestemperatureand atmospheric pressure - barometer sensors, including altitude. It is used to improveGPSpositioning or to realize 3D navigation in rooms withIMUsensor. Application of BMP280 chip makes the sensor small, compact and withlow power consumption. Measuring range for temperature isfrom 0°C to 65°Cwith an accuracy of +/- 0.01°C and for atmospheric pressurefrom 300 hPa to 1100 hPa with relative measurement accuracy of +/- 0.12 hPa.
