Description

• 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.
