The BMP180 is a high-precision digital barometric pressure sensor, perfect for measuring absolute pressure in your environment. It’s ideal for applications like determining the altitude of your robot, drone, or projectile by converting pressure data into altitude with impressive accuracy—up to 1 meter, and noise as low as 17 cm in ultra-high resolution mode.
This sensor is highly efficient, operating at just 0.3 µA, making it a great choice for low-power, battery-operated projects. Fully calibrated and ready to use out of the box, the BMP180 communicates via I2C and outputs 16-bit pressure and temperature data.
For added convenience during prototyping, the module includes optional I2C pull-up resistors that can be enabled via the PU (pull-up) jumper on the board. Built-in calibration data ensures accurate, temperature-compensated altitude calculations with minimal setup.
