BMP180 Digital Barometric Air Pressure Sensor

BMP180 Digital Barometric Air Pressure Sensor

The BMP180 pressure sensor is a digital output sensor that measures the air pressure in the environment. It is a compact and highly practical product. It measures pressure between 300 and 1100 hPa and provides altitude information in the +9000 to -500 m range. It communicates with different microcontrollers and development boards via the I2C protocol. It is a sensitive sensor suitable for use in various projects, from weather station projects to multicopters.

We previously made a mini weather station project using the BMP180 sensor. You can access the blog post of the related project by clicking here. You can also build a weather station with the BMP180 sensor and easily measure different meteorological data.
