Bosch BMP180 & BMP085

This is an Arduino library for Bosch BMP180 & BMP085 barometric pressure & temperature sensor

  • Supply voltage: 1.8v - 3.6v
  • Range: 30,000Pa..110,000Pa at 0°C..+65°C
  • Typ. resolution: 1Pa / 0.1°C
  • Typ. accuracy: ±100Pa / ±1.0°C
  • Typ. relative accuracy: ±12Pa / xx°C

Supports all* sensors features & more:

  • Read & calculate compensated temperature**, in °C
  • Read & calculate compensated barometric pressure**, in Pa
  • Reset
  • Read chip ID
  • Read chip FW version
  • Calculate sea level pressure, in Pa
  • Convert barometric pressure to hPa, mmHg, inHg
  • Convert sea level pressure to hPa, mmHg, inHg
  • Simple forecast: thunderstorm, rain, cloudy, partly cloudy, clear, sunny

Important recommendations:

  • Measurement of atmospheric pressure depends on the ambient temperature. Avoid placing the BMP180 in front of a heat source.
  • Do not expose the BMP180 to airflow from a fan, as this may lead to unstable measurements.
  • The sensor is sensitive to moisture and is not recommended for direct contact with water.
  • BMP180 is sensitive to light. Do not expose the sensor to direct light.
  • Do not exceed the supply voltage.

Tested on:

  • Arduino AVR
  • Arduino ESP8266
  • Arduino STM32

*EOC pin is not used, shows the end of conversion

*XCLR pin is not used, reset pin

**Library returns 255, if there is a communication error has occurred
