Small, compact - BMP180 - digital atmospheric pressure and temperature sensor. No matter if You are building weather station or drone this sensor will be handy. I2C interface and low power consumption (as low as 5 µA in standard mode and 0.1 µA in standby mode) make them a good choice for Your application.

Small (only 10.5 x 13 mm) board with the BMP180 sensor. This is I2C (TWI) sensor for measuring atmospheric pressure and temperature. It is used in weather stations and in all flying devices (drones) to read altitude.
Warning - I2C lines are not protected by any converter, so You will need some bidirectional logic level converter (like this or this) to get the board working with Arduino. You can connect module directly to microcontrollers running on 3.3V like Raspberry Pi or Teensy 3.2.
You can power module with 5V, there is 3.3V regulator on board. In this design Vdd = Vddio, and according to BMP180 datasheet maximum voltage on SDA/SCL pins is equal Vddio. Since it is only 3.3V connecting module to Arduino running on 5V TTL means You are working outside voltage specified in BMP180 datasheet. It may work or it may get damaged, YMMV. We recommend using logic level converter with an Arduino.
