Check the listing for details. BMP180 GY-68 Barometric Pressure Altitude I2C Sensor Module. Condition: New. Listed at 5.99 USD. BMP180 GY-68 Barometric Pressure Altitude I2C Sensor Module The BMP-180 is a high precision, miniature, ultra-low power pressure sensor for DIY electronics and mobile devices. Its performance and absolute accuracy can reach the lowest 0.03hPa, and the power consumption is very low, only 5μA. The BMP180 is packaged in an 8-pin ceramic leadless chip carrier (LCC) ultra-thin package and the module can be connected directly to a variety of microprocessors and microcontrollers via the I2C bus. By measuring the absolute pressure of the environment using the BMP180 and converting the pressure measured into altitude, you have a reliable sensor for determining the height of your robot, plane or UAV. The BMP180 comes fully calibrated and ready to use. The device operates over I2C and the module includes the I2C pull up resistors for your convenience and ease during breadboarding. Using I2C, the device provides pressure and temperature as 16bit values, which are used along with calibration data within the device to provide a temperature compensated altitude calculation.
