BMP180 Barometric Pressure Sensor For Arduino


BMP180 Digital Barometric Pressure Sensor Board Module Arduino Compatible Measuring the absolute pressure of the environment using a digital barometer such as this has some interesting applications. By converting the pressure measured into altitude, you have a reliable sensor for determining the height of your robot, plane, or projectile! Using a sensor as capable as the BMP180 you can achieve an accuracy of 1m, with the noise of only 17cm in ultra-high-resolution noise.

The device will operate at only 0.3uA meaning a 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. Using I2C, the device provides pressure and temperature as 16bit values, which are used along with calibration data within the device are used to provide a temperature compensated altitude calculation

  • Weather forecasting: The BMP180 Barometric Pressure Sensor is commonly used in weather forecasting and meteorological applications. It provides accurate measurements of atmospheric pressure, which is a key parameter for predicting weather patterns and changes.
  • Altitude measurement: The sensor can be utilized for altitude measurement in various applications such as aviation, mountaineering, and unmanned aerial vehicles (UAVs). By measuring changes in atmospheric pressure, it can estimate the altitude of the sensor or the device it is integrated with.
  • Indoor and outdoor navigation: The BMP180 sensor can aid in navigation systems that require altitude information, such as GPS devices or drones. It enables precise positioning and altitude tracking for accurate navigation both indoors and outdoors.
