Digital Barometric Pressure Sensor Module (GY-68 BMP180)

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.
