Gravity I2C BMP280 Barometer Sensor SKU SEN0226 Introduction The upgraded Pressure & Altitude Sensor Gravity BMP280 by DFRobot has the functions both on detecting temperature and air pressure. It can be connected to Arduino, and controlled by Arduino code. Compared to the old edition BMP180, BMP280 has lower power consumption, more precise measurement, lower noise and higher sampling frequency. Normally, pressure sensors measure the air pressure and the temperature. Because of the relation between the air pressure and the altitude, we can use the air pressure sensor to measure the altitude and the building height. BMP280 is also suitable for navigation, by the use of Inertia Measurement Unit IMU , BMP280 can be used in GPS refinement, 3D in-door navigation and floor detection. The BMP280 is based on Bosch’s proven Piezo-resistive pressure sensor technology featuring high EMC robustness, high accuracy and linearity and long term stability. The relative accuracy is hPa, which is equivalent to ±1 m difference in altitude. The operating temperature range for long tern stability is 0 ~65 Attention because the sensor is very sensitive to the environment, please don’t touch it. • Enhancement of GPS navigation e.g. time-to-first-fix improvement, dead-reckoning, slope detection • Indoor navigation floor detection, elevator detection • Outdoor navigation, leisure and sports applications • Weather forecast • Health care applications e.g. spirometry • Vertical velocity indication e.g. rise/sink speed Specification • Operating Voltage 3.3V/5V • Operating Current 2.7µA 1 Hz sampling frequency • Pressure Measurement Range 300 ~ 1100 hPa equivalent to m above/below sea level • Relative Accuracy hPa, equiv. to ±1 m • Temperature Measurement Range 0 ~65 • Temperature Accuracy • Operating Temperature range ~+85 • Dimension 30mm22mm • Interface Gravity-I2C 4pin • Weight 12g Board Overview Gravity I2C BMP280 Baromete r Sensor Label SDA SCL GND VCC Description I2C Data I2C Clock GND 3.3/5V Tutorial To measure the air pressure and temperature of the local environment, and calculate the altitude of the sensor.
