The BMP180 is a very small sensor that is used to measure pressure in many robots and electronic projects. It measures the pressure of the water and gives digital output to the controller. This small sensor can measure the pressure values between 300-1100hPa. It also gives information about the altitude between 500 and 9000 meters. We will talk about the connection and codes of this sensor which is used in air vehicles such as drone in this writing.
Compatible with many microcontroller systems, especially Arduino. Input Voltage: 3.3V (1.8-3.6V) Supports I2C protocol. Very precise height measurement up to ± 25cm 14x12mm very small card size
