BMP085 Digital Barometric Pressure Sensor (GY-65)

BMP085 Digital Barometric Pressure Sensor (GY-65) info

BMP085 Digital Barometric Pressure Sensor (GY-65) is a carrier board based on BMP085 digital pressure sensor chip. This 3-5V high-precision, ultra-low power consumption sensor can be used in mobile devices. The lowest absolute accuracy can reach 0.03hPa, and the power consumption is very low, at only 5μA.

Typical Applications:

• GPS pinpoint navigation (dead reckoning, fluctuation bridge detection)
• Indoor and outdoor navigation
• Detection for entertainment, sports, health care
• Weather forecast
• Vertical speed instruction (rise/sink speed)
• Fan power control
