LibBMP085 is a simple, easy to use C library for communication with Bosh BMP085/BMP180 barometric pressure and temperature sensor on Linux. It provides access to the BMP085/BMP180 sensor from the user space through the /dev interface. Module i2c-dev must be loaded before library use.
- Bosh BMP085;
- Bosh BMP180 (replacement for BMP085).
The library implements functions for:
- connecting to BMP085/BMP180 sensor over I2C bus;
- reading the sensor calibration table;
- reads measured values from the sensor;
- calculating relative altitude change. It supports all BMP085/BMP180 modes of operation.
Installation instruction can be found in the INSTALL file.
Tested on Raspberry Pi model B Revision 1 board with:
- Adafruit BMP085 module (Adafruit product ID 391);
- Adafruit BMP180 module (Adafruit product ID 1603). The library is distributed with an example program that demonstrates the library use for temperature and barometric pressure measurement.
