BMP180 Barometric Pressure Sensor Module (GY-68) -5pin

Key Features

✅ High Accuracy & Resolution

• Measures barometric pressure (300–1100 hPa) with ±0.12 hPa accuracy.

• Temperature measurement range: -40°C to +85°C (±0.5°C accuracy).

• Supports ultra-high-resolution mode (up to 0.03 hPa).

✅ Altitude Measurement

• Calculates altitude based on pressure changes (relative to sea level).

• Useful for drones, weather balloons, and outdoor navigation systems.

✅ Low Power Consumption

• Ideal for battery-powered devices with optimized power modes.

✅ I2C Interface (5V Tolerant)

• Simple 2-wire communication (SDA & SCL).
