Briefly introduced: The air pressure sensor BMP085 (GY-65 breakout board) with an additional temperature sensor

The GY-65 is a simple breakout board for Bosch BMP085 barometric pressure sensor with integrated temperature measurement. The values ​​can be a simple used for weather forecast, more precise (GPS) navigation (level measurement, as well as vertical climb and descent).

BMP085 breakout board (GY-65) air pressure and temperature sensor

Specifications:

  • Bosch BMP085 pressure sensor with additional built-in temperature sensor
  • 300 – 1100 hPa (-500m to 9000m altitude)
  • Resolution up to 0.03 hPa (0.25 m)
  • Temperature measurements from 0 – 65 ° C
  • Temperature compensation
  • Response time measurement: 7.5 ms
  • I²C interface
  • 5V power supply with a 3.3V voltage regulator on the breakout board
