Good but needs 3.3V logic
Sensor works well, but make sure your microcontroller supports I2C properly. Had to check wiring twice.

Low power consumption
Exactly what I needed for a battery-powered logger. Sleep mode works as expected.
5 FAQ
Q: What is the I2C address?
A: The default I2C address is 0x77.
Q: Can I connect this directly to a 5V Arduino?
A: Yes, the module includes a voltage regulator, but logic level shifting is recommended for SDA/SCL lines.
Q: Is this sensor waterproof?
A: No, the chip is exposed. Please house it in a waterproof enclosure with a vent for pressure equalization.
Q: Which library should I use?
A: The Adafruit BMP085 Library is fully compatible with the BMP180 chip.
Q: Can it measure altitude accurately?
A: It provides relative altitude based on pressure. Calibration with local sea level pressure improves accuracy.
