Bmp180 pressure sensor GY68 GY-68 BMP180 BMP 180 Digital Barometric Pressure Sensor Board Module compatible with BMP085

Bmp180 arduino sensor 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! Bmp180 is soldered onto a PCB with a 3.3V regulator, I2C level shifter and pull-up resistors on the I2C pins. BMP180 is Bosch's next generation of sensors and replaces the BMP085. In terms of firmware / software, the good news is that it is absolutely similar to the BMP085. According to bmp180 datasheet, the XCLR pin is not physically present on the BMP180 so if you need to know that data is ready you will need to query the I2C bus.
