Description
The GY-68 BMP180 Atmospheric Pressure Sensor Module is a compact digital barometric sensor designed for accurate measurement of atmospheric pressure and temperature, with pressure readings also suitable for calculating approximate altitude.
The module uses the BMP180 sensor and communicates through the I²C interface, making it easy to integrate with microcontrollers and development boards. An onboard 3.3V regulator allows the module to be powered from a 5V supply while providing the appropriate voltage for the sensor.
With low power consumption, low noise, and factory calibration, the GY-68 BMP180 is suitable for navigation, weather monitoring, altitude measurement, and various DIY electronics projects.
