Raspberry Pi for BME280



BME280, the precision sensor from Bosch, is soldered onto PCB. Not only the pressure and the temperature, this sensor can measure humidity.  It uses both I2C and SPI (supports 3-, 4-wire SPI) interface.

Specifications:
  • Supply Voltage: 1.8 - 3.3 V DC
  • Interface: I2C (up to 3.4MHz), SPI (up to 10 MHz)
Operational range:
  • Temperature: -40 to +85°C
  • Humidity: 0-100%
  • Pressure: 300-1100 hPa
Resolution:
  • Temperature: 0.01°C
  • Humidity: 0.008%
  • Pressure: 0.18Pa
Accuracy:
  • Temperature: +-1°C
  • Humidity: +-3%
  • Pressure: +-1Pa
I2C address
  • SDO LOW : 0x76
  • SDO HIGH: 0x77
Includes
  • Sensor module x 1
  • 1x7 male header x 1
