DescriptionBMP180 measures the absolute pressure of the air around it. It has a measuring range from 300 to 1100hPa with an accuracy down to 0.02 hPa. It can also measure altitude and temperature.The BMP180 barometric sensor communicates via I2C interface. This means that it communicates with the Arduino using just 2 pins (SCL and SDA).The device will operate at the only 0.3uA meaning low current draw for battery-powered applications. The BMP180 comes fully calibrated and ready to use. As the device operates over I2C we’ve added optional I2C pull-ups that can be enabled using the PU (pull up) jumper on the board for your convenience and ease during breadboarding.Features :Operating Voltage: 1.8V to 3.6V Supply Voltage.Input voltage of BMP180MODULE: 3.3V to 5.5VPeak current : 1000uAMaximum voltage at SDA , SCL : VCC Voltage 0.3V MaxI2C interface.Fully calibrated.Very low noise – up to 0.02hPa (17cm)Small and easy to use.Pin details of BMP180 to connect with Arduino:It is similar to all other I2C Devices. You can either use the dedicated I2C Pins or the A4 and A5 pins that are mapped to I2C in Arduino UNO.
