Function: High-precision digital barometric pressure and temperature sensor module designed for environmental monitoring, weather stations, and altitude measurement.

Sensor Chip: Built around the Bosch BMP180 sensor, capable of measuring pressure and temperature with high accuracy and low power consumption.

Operating Voltage: Works on 3.3V–5V DC, making it fully compatible with Arduino, Raspberry Pi, and other microcontroller platforms.

Interface: Communicates via I²C protocol for easy and reliable data transfer using just two pins (SCL and SDA).

Performance: Measures barometric pressure from 300 to 1100 hPa (equivalent to altitudes from +9000m to -500m) with accuracy up to ±1 hPa.

Construction: Compact GY-68 breakout board featuring onboard voltage regulator and pull-up resistors for stable readings and direct MCU interfacing.

Applications: Ideal for weather monitoring systems, drone altitude control, GPS correction, environmental logging, and DIY IoT projects.

Design: Small, lightweight module with clearly labeled pin headers for quick breadboard or jumper wire connections.
