BMP180 Digital Barometric Pressure Sensor Board Module (Barometric sensor)
Description:

This digital barometer has some interesting applications. By measuring the absolute pressure of the environment and converting this into altitude. you will have a reliable sensor for determining the height of your robot, plane or projectile. This sensor is capable of achieving an accuracy of 1m, with noise of only 17cm in ultra-high resolution. The device will operate at only 0.3uA meaning low current draw for battery powered applications.

1.8V to 3.6V Supply Voltage
Low power consumption - 0.5uA at 1Hz
I2C interface
Max I2C Speed: 3.5 MHz
Very low noise - up to 0.02hPa (17cm)
Fully calibrated
Pressure Range: 300hPa to 1100hPa ( 9000m to -500m)
Weight: 1.18g
Size: 21mm x 18mm

Package includes:

1 x BMP180 Digital Barometric Pressure Sensor Board Module
1 x Male to Male 4 pin header
