I have tried to find an Eagle library that include two commonly used sensors, BMP180 and 5528, but I haven't succeed. As these components are common used in Arduino/RaspberryPi projects, I assume that there exists some library for them already. Actually, the schematics for these components aren't that complicated.
These are the sensors that I'm looking for:
GY-68 BMP180 pressure sensor:
5528 light intensity sensor:
