BMP180 barometric temperature sensor driver

1, Introduction to BMP180

The BMP180 is the best low-cost sensing solution for measuring barometric pressure and temperature.The sensor is soldered on a PCB with a 3.3V regulator, I2C level shifter, and pull-up resistors on the I2C pins.The BMP180 replaces the BMP085.

BMP180 has the following features:

• Pressure sensing range: 300-1100 hPa (9000m to -500m above sea level)
• Resolution up to 0.03hPa / 0.25m
• -40 to +85°C operating range, ±2°C temperature accuracy

In the previous article, the BMP180 was introduced, please refer to:
