BMP085 is a  kind of pressure sensor  with  high precision, low energy, which can be used in mobile devices. Its excellent 
performance  makes the absolute precision reach the minimum0.03hPa, and it is with very low power consumption, only 3u A. sing powerful 8-pin ceramic leadless chip carrier ( LCC ) thin package, BMP085  can be connected directly with a variety of microprocessor s through I2C bus .

Main features:
Pressure range: 300 － 1100hPa (at an altitude of 9000 meters to 500 meters)
Supply voltage: 1.8V － 3.6V （ VDDA ） 1.62V － 3.6V （ VDDD ）
LCC8 package:ceramic leadless chip carrier(LCC)
Size: 5.0mmx5.0x1.2mm
Low consumption:  5 μ A in standard mode
High accuracy:resolution ratio is 0.06hPa (0.5 meter) in low power consumption mode; 0.03hPa (0.25 meter) in high linear mode
Temperature output
12C interface
Temperature compensation
Leadless,accord with RoHS standard
MSL 1
Response time:7.5ms
Standby current: 0.1 μ A
No need for external clock circuit

  Support our scratch driver software, can be easy use in scratch

1. command "bmp085init"  initial bmp085 sensor

2. after broadcast ""Update"    in Sensing --> Slider ,

you will see the " EAlt" "Epressure" "ETemp"  in the list
