Description:

The GY-68 BMP180 module provides high-accuracy barometric pressure and temperature measurements. This digital barometer is perfect for determining altitude, offering 1m accuracy with only 17cm of noise in ultra-high resolution mode. The BMP180 is factory-calibrated and ready to use, communicating via I2C for easy integration with microcontrollers. On-board I2C pull-up resistors (selectable via jumper) simplify circuit design. The module provides 16-bit pressure and temperature values, which, combined with internal calibration data, enable temperature-compensated altitude calculations. Low power consumption (0.3uA) makes it suitable for battery-powered devices.

Specifications:

• Supply Voltage: 1.8V to 3.6V
