BMP180 Digital Barometric Pressure Sensor

This precision sensor is the best low-cost sensing solution for measuring barometric pressure and temperature. Because pressure changes with altitude you can also use it as an altimeter! The sensor is soldered onto a PCB with a 3.3V regulator, I2C level shifter and pull-up resistors on the I2C pins.

Size: 21mm x 18mm
1.8V to 6V Supply Voltage
Max I2C Speed: 3.5Mhz
Low power consumption – 0.5uA at 1Hz
I2C interface
Very low noise – up to 0.02hPa (17cm)
Full calibrated
Pressure Range: 300hPa to 1100hPa (+9000m to -500m)
