BMP280 Barometric Pressure + Temperature Sensor, calibrated Barometer/Altimeter, I2C, SPI for Arduino & Raspberry Pi

BAROMETRIC PRESSURE MEASUREMENTS - Measure the atmospheric pressure from 300 hPa to 1100 hPa which equals an altitude of 9000 m to -500 m above sea level with the BMP280 sensor from Bosch. It has a high resolution of 0.16 Pa. TEMPERATURE MEASUREMENTS - The temperature can be measured between -40 °C and 85 °C with a resolution of 0.01 °C and an accuracy of ± 1.0 °C. The measuring frequency is 157 Hz and has been increased compared to its predecessor. HIGH PRECISION SENSING - The sensor has already been calibrated for you. Just connect it to your microcontroller board and start measuring without fitting curves. As an altimeter you can measure altitude changes with ±1 meter accuracy. EASY ACCESS - The BMP280 breakout board can easily be used with any microcontroller like Arduino or Raspberry Pi running at an operating voltage of 1.8 V to 3.6 V. Communication between sensor and device is done via I2C or SPI . EASY UPGRADE - The BMP280 sensor from Bosch is the successor of the seasoned chipsets BMP085, BMP180 and BMP183. Switch to BMP280 now to benefit from increased precision, accuracy and reduced measurement noise.
