The Octopus BMP180 Barometric Pressure Sensor is a high precision, small volume pressure sensor. Factory-calibrated to have a -40°C to +85°C operational range, ±2°C temperature accuracy.
It is built around the Bosch BMP180 digital pressure sensor, which measures air pressure and temperature and is read over an I2C interface. Typical uses include weather stations and estimating altitude.
