BMP180 pressure sensor:

The BMP180 is a digital pressure sensor manufactured by Bosch Sensortec. It is designed to measure atmospheric pressure and temperature. The BMP180 sensor provides both pressure and temperature data via an I2C interface, making it relatively easy to interface with microcontrollers and other digital systems.

Key features of the BMP180 sensor include:

1. Pressure Range: The BMP180 sensor can measure atmospheric pressure in a range from 300 hPa to 1100 hPa (or 9000 meters to -500 meters above sea level with a resolution of 0.01 hPa.
2. Temperature Measurement: It also provides temperature measurements with a resolution of 0.1°C.
3. Low Power Consumption: The BMP180 sensor is designed for low power consumption, making it suitable for battery-operated devices.
4. Small Size: It comes in a compact package, making it suitable for space-constrained applications.
5. Digital Interface: Communication with the BMP180 sensor is done via the I2C interface, allowing easy integration with various microcontrollers and systems.
