GY-68 BMP180 Barometric Pressure and Temperature Sensor Module

The GY-68 BMP180 Barometric Pressure and Temperature Sensor Module is a high-precision, low-power digital sensor designed for environmental sensing. Powered by the advanced Bosch BMP180 silicon piezo-resistive sensor chip, it measures barometric pressure from 300 to 1100 hPa and ambient temperature with high accuracy. This module serves as a direct, upgraded replacement for the older BMP085 sensor, offering superior stability, lower noise, and faster response times for altitude tracking and weather monitoring.

This dual-hole PCB version is highly compact and easy to mount, making it ideal for indoor/outdoor navigation, weather forecasting, sports devices, and vertical velocity indicators (rise/sink speed). It communicates via a standard I2C interface, ensuring seamless compatibility with popular microcontrollers like Arduino, ESP32, ESP8266, STM32, and Raspberry Pi. Whether you are building an IoT weather station, a DIY drone altimeter, or a smart wearable, the GY-68 BMP180 provides reliable, real-time atmospheric data.

Features:

• High Precision Sensing: Measures barometric pressure from 300 hPa to 1100 hPa (+9000m to -500m relating to sea level).
• Ultra-low Power Consumption: Draws only 0.5 µA in standard mode, making it perfect for battery-powered IoT devices.
• Integrated Temperature Sensor: Provides accurate ambient temperature readings alongside pressure data.
• Standard I2C Interface: Easy 2-wire communication with pull-up resistors onboard.
• Dual-Hole PCB Design: Features two mounting holes for secure mechanical installation in custom enclosures.
• Fully Calibrated: Factory-calibrated sensor with internal compensation algorithms.
