Rs- Pi BMP085 Barometric Pressure/Temp/Altitude Sensor
Release date
Description
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)
