Description

One of the most common sensors for measuring the pressure and altitude is  BMP180.  This is a BMP-180 based digital barometric pressure sensor module and is functionally compatible with the older BMP-085 digital pressure sensors with less power consumption smaller in size and more accurate. The most important features of this module are as follow:

Application :  

1. Enhancement of GPS navigation (dead-reckoning, slope detection, etc.)
2. In- and out-door navigation
3. Leisure and sports
4. Weather forecast
5. Vertical velocity indication (rise/sink speed)

Features:

1. Can measure temperature and altitude.
2. Pressure range: 300 to 1100hPa
3. High relative accuracy of ±0.12hPa
4. Can work on low voltages
5. 3.4Mhz I2C interface
6. Low power consumption (3uA)
7. Pressure conversion time: 5msec
8. Potable size
