  • Incredible resolution and sensitive barometric pressure sensor
  • I2C interface for easy Arduino connection
  • Pressure and temperature sensor combined
  • Pressure sensor range: 10 to 2000 mbar (0.145 to 29 psi)

The Barometric Pressure Sensor Module is a highly sensitive barometric pressure sensor for weather, industrial, rocketry, balloon, and many other pressure sensing applications. The sensor is designed for use as a micro-altimeter so it has incredible resolution and is so sensitive that it can detect an altitude change of just 13cm. By moving it up and down the changes in output values can be changed.
