BMP180 I2C Digital Barometric Pressure Sensor Module

The BMP180 digital barometric pressure sensor module measures atmospheric pressure from 300 to 1100 hPa with exceptional accuracy and ultra-low power consumption. Operating over a simple I2C interface, it comes factory-calibrated and ready to integrate into your electronics builds. It is an ideal component for makers, students, and hobbyists creating altimeters, weather stations, and robotics projects.

Accurate pressure and altitude sensing

Featuring a wide measuring range from 300 to 1100 hPa (+9000 m to -500 m altitude equivalent), this module utilises piezo-resistive technology for high accuracy, ruggedness, and long-term stability. In advanced resolution mode, it achieves very low noise down to 0.02 hPa (17 cm).

Factory calibrated with I2C support

The sensor comes fully factory-calibrated with all necessary calibration coefficients pre-stored in ROM. It communicates directly via an I2C interface supporting bus speeds up to 3.5 MHz, offering functionality nearly identical to its predecessor, the BMP085.

Compact and energy efficient

Designed for low-power operation, the module draws as little as 0.5 uA at 1 Hz on a 1.8 V to 3.6 V supply. Its compact 13 mm x 10 mm footprint allows it to easily fit into space-constrained projects.

What is included

Includes 1 x GY-68 BMP180 sensor module.
