BMP180 is a high precision pressure sensor.In this project，we will use Arduino to get atmosphere pressure, temperature and altitude from BMP180 sensor and display these value in Arduino IDE serial window.
2)Parts and devices：
1 x arduino UNO R3
1 x BMP180 pressure sensor
1 x Jumper wires
3) Circuit graph：
4) Download sample code from following link：
Unzip downloaded file from above link, load it into Arduino IDE.
In arduino IDE serial monitor window, you will see environment temperature, atmosphere pressure, and altitudeas per following pictures:
