BMP180 GY-68 Barometric Pressure Sensor Module

The BMP180 GY-68 Barometric Pressure Sensor Module is a breakout board built around Bosch’s BMP180 digital barometric pressure sensor, delivering precise pressure and temperature readings for altitude sensing, weather stations, and GPS enhancement. Its small footprint and low power draw make it easy to add to any microcontroller-based project.

Key features:

• High Precision: Measures absolute pressure with a resolution down to 0.03 hPa, equivalent to about 25cm of altitude change.
• Wide Pressure Range: Operates from 300 hPa to 1100 hPa, covering altitudes from -500m to +9000m.
• I2C Interface: Communicates over the standard two-wire I2C bus for easy connection to Arduino, ESP8266, and similar boards.
• Integrated Temperature Sensing: Provides temperature-compensated readings alongside pressure data.
• Low Power Consumption: Ultra-low power design suits battery-powered weather and altitude-tracking projects.
• Onboard Voltage Regulation: Accepts 3.3V to 5V input despite the BMP180 chip’s native 1.8V to 3.6V logic.
