What it does

The BMP180 Digital Barometric Pressure Sensor Module is a high-precision digital barometric pressure and temperature sensor. It can measure absolute pressure and calculate altitude, making it ideal for weather stations, navigation systems, and altitude tracking applications.

Key features

  • Measures barometric pressure with 0.02hPa resolution
  • Measures temperature for compensation and weather data
  • Calculates altitude from sea-level pressure reference
  • I2C digital interface for easy microcontroller connection
  • Low power consumption suitable for battery projects
  • Wide pressure range from 300hPa to 1100hPa
  • Compact size for easy integration

Good to know

  • Module includes 3.3V regulator for 5V input compatibility
  • Use Adafruit_BMP085 library (BMP180 is software-compatible)
  • For altitude accuracy, set local sea-level pressure as reference
  • BMP180 is deprecated; BMP280 is newer alternative with same footprint
  • Pressure readings affected by air conditioning and weather patterns
