Adding a pressure sensor to a Raspberry Pi. via conorfarrell
I’ve been working on a prototype for a Raspberry Pi weather station this last while and recently I made two new additions to the setup: a pressure sensor and an LCD screen.
The pressure sensor is the BMP180, which also gives a temperature reading. I used the Adafruit BMP libraries to control it (you can find the project on Github at https://github.com/adafruit/Adafruit_Python_BMP). There are plenty of guides online in getting this sensor set up, and it’s straightforward to do.
I was already using the Adafruit DHT library to use the temperature and humidity sensor and send data to Google Docs, so I just added in the imports and stuff to its Google upload script so that both the DHT and BMP stuff could be used in one file.
