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
