BMP180 Interfacing with Arduino in Depth

8 Feb 2017

This video is all about interfacing BMP180 module with Arduino. BMP180 will help us to measure environmental temperature and pressure and by using that we can calculate the altitude which can be used in various applications like weather monitoring, navigation etc. The BMP180 sensor module comes with I2C interface and with a default address 0x77 which is not configurable limiting stacking of multiple modules to that same I2C bus. In this tutorial we will interface the module with Arduino by using I2C interface that is analog input pin A4 and A5. And for this we are not going to use any library although if you are interested you can use any library available online which are actually pretty easy to use. Interfacing the module without any library will help us learn how it works as well as we can interface to other devices also where libraries are not available.
