BMP180 Barometric Pressure Sensor


This precision sensor from Bosch is the best low-cost sensing solution for measuring barometric pressure and temperature. Because pressure changes with altitude you can also use it as an altimeter! The sensor is soldered onto a PCB with a 3.3V regulator, I2C level shifter and pull-up resistors on the I2C pins.

Measuring the absolute pressure of the environment using a digital barometer such as this has some interesting applications. By converting the pressure measured into altitude, you have a reliable sensor for determining the height of your robot, plane or projectile.

  • Pressure range: 300 ~ 1100 hPa (altitude 9000 m ~ – 500 m)
  • Compatible with 3.3V and 5V
  • LCC8 encapsulation: lead-free ceramics carrier encapsulation (LCC)
