=='''Introduction'''==
[[File:Bmp180Zz.jpg]]<br> 
The BMP180 is the function compatible successor of the BMP085, a new generation of high precision digital pressure sensors for consumer applications.<br>
The ultra-low power, low voltage electronics of the BMP180 is optimized for use in mobile phones, PDAs, GPS navigation devices and outdoor equipment. With a low altitude noise of merely 0.25m at fast conversion time, the BMP180 offers superior performance. The I2C interface allows for easy system integration with a microcontroller.<br>
The BMP180 is based on piezo-resistive technology for EMC robustness, high accuracy and linearity as well as long term stability.<br>
The BMP180 chip only accepts 1.8V to 3.6V input voltage,however It contains a built-in stabilivolt (3.3V), thus being able to work under 5V. Therefore, it can be used on Arduino without any debugging。<br>
The schematic diagram of the module is as follows:<br>

=='''Features'''==
1)	BMP180 is a high-precision, small-sized and ultra-low-power barometer. It is applicable to mobile devices.<br> 
2)	It contains a built-in stabilivolt (3.3V), thus being able to work under 5V.<br>  
3)	PCB size: 2.3 x 2.3 cm.<br>  
4)	 Excellent performance. Its absolute accuracy can be down to 0.03 hPa. Ultra low power consumption as 3μA.<br>  
5)	Pressure range: 300~1100hPa (9000 to 500 meters elevation)<br> 
6)	 With temperature output and an I2C bus.<br>  
=='''Application'''==
*GPS precision navigation (dead reckoning, bridge detection etc.)<br>
*Indoor/Outdoor navigation<br>
*Monitoring in entertainment, sports, and healthcare<br>
* Weather forecast<br>
*vertical speed indication (ascending and descending rate)
