BMP180 Digital Barometric Sensor Module compatible with Arduino will measure the absolute pressure of the environment using a digital barometer. This sensor module utilizes the advanced Bosch BMP180 sensor, synonymous with high accuracy and stability in pressure and temperature measurements. As an exceptional barometric pressure sensor, it's ideal for various applications such as weather monitoring and altimetry. By converting measured pressure into altitude, the BMP180 can determine the height of your robot, plane, or projectile with an impressive accuracy of 1m and a noise level of only 17cm in ultra-high resolution. Consuming only 0.3uA, this bmp180 barometric pressure sensor module is perfect for battery-powered applications. The bmp180 sensor comes fully calibrated and ready to use and operates over an I2C interface. Optional I2C pull-ups can be enabled using the PU (pull-up) jumper on the board for easy breadboarding. With this barometer bmp180, pressure and temperature are provided as 16-bit values, used for temperature-compensated altitude calculations.
The barometric pressure sensor BMP180 is ideal for use in various real-world applications. It's extensively used as an air pressure transducer for measuring atmospheric pressure and converting it to altitude, particularly beneficial in aircraft and drones to determine relative altitude. It is also suitable for air pressure measuring instruments in weather monitoring systems and GPS navigation enhancement. The digital barometer’s compatibility with Arduino boards facilitates quick prototyping and development of sensor-based projects, providing insights into altitude changes essential for navigation and scientific studies. Additionally, the barometric sensor serves well for indoor and outdoor navigation and environmental data logging applications.

To effectively use the BMP180 Barometric Pressure Sensor, begin by connecting it to your development board, such as an Arduino. This baro pressure sensor has several pinouts: VCC, GND, SCL (clock), and SDA (data). Use the I2C interface to connect the bmp180 to the Arduino. You can use the I2C pull-up jumpers on the board if necessary. Once connected and powered, utilize the sensor's library to initialize communication. With the sensor initialized, retrieve pressure and temperature readings. These readings can be used in sensor barometric pressure calculations to calculate altitude by applying the correct formulas or using existing libraries. Ensure you use the correct calibrated data from the sensor for temperature compensation to achieve accurate altitude measurements. The provided calibration data ensures accurate atmospheric pressure measuring instruments performance.
