BMP085 Barometric Pressure Sensor is a board with precision sensor from Bosch is the best low-cost sensing solution for measuring barometric pressure and temperature. The BMP085 is a high-precision, ultra-low power barometric pressure sensor. It offers a measuring range of 300 to 1100 hPa with an absolute accuracy of down to 0.03 hPa. The BMP085 is based on piezo-resistive technology for EMC robustness, high accuracy and linearity as well as long term stability. Because pressure changes with altitude you can also use it as an altimeter! The sensor is soldered onto a PCB with a filter capacitor and two pull-up resistors on the I2C pins.
