BMP180 – Atmospheric Pressure Sensor

GY-68 BMP180 BMP-180 Digital Barometric Pressure Sensor Module

GY-68 BMP180 BMP-180 Digital Barometric Pressure Sensor Module 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. The BMP180 is the next-generation of sensors from Bosch, and replaces the BMP085
