GY-68 BMP180 Atmospheric Pressure Sensor Module

The GY-68 BMP180 is a compact, high-precision digital barometric pressure sensor module — an improved, lower-power replacement for the BMP085. It measures barometric pressure, temperature, and altitude and is ideal for weather stations, altimeters, UAVs, and environmental-monitoring projects. The on-board I²C interface makes it easy to connect to Arduino, ESP32, ESP8266, Raspberry Pi, and other microcontrollers. An on-board 3.3V regulator provides compatibility with 5V systems.

Core Capabilities

• Measures pressure, temperature, and altitude in one compact module
• Ultra-low power consumption — ~0.5 µA at 1 Hz
• High resolution / very low noise — down to 0.02 hPa (~17 cm)
• Wide pressure range: 300 hPa to 1100 hPa (≈ +9000 m to -500 m relative to sea level)
• I²C digital interface — easy MCU integration
• On-board 3.3V LDO regulator — compatible with 3.3V and 5V systems
• Fully calibrated sensor for out-of-the-box use
