Great for learning I2C protocols
Bought this for a university sensor project. The documentation online is plentiful, making it easy to get started. The temperature compensation feature is a nice bonus.

Good value, accurate enough for altitude hold
Used this on a custom quadcopter build. It provides stable altitude data which helps significantly with hover stability. Just make sure you use the correct voltage regulator if running at 5V logic.

Works perfectly with ESP32
Connected this to an ESP32 for a smart home dashboard. The I2C address is standard, so no conflicts with other sensors. Data transmission is fast and reliable over WiFi.

Solid module, small footprint
The size is perfect for compact enclosures. Soldering the headers was easy. Only giving 4 stars because the silkscreen labeling is slightly faint, but otherwise a great product.

Reliable pressure readings
I have been logging data for two weeks straight without any issues. The sensor responds quickly to pressure changes when I open windows or doors. Very satisfied with the purchase.

Perfect replacement for my old BMP085
This module works flawlessly with my Arduino Uno. The library support is excellent, and the readings are consistent with my local weather station data. Highly recommended for DIY barometer projects.
Q: Is this module compatible with 5V Arduino boards?
A: Yes, the GY-68 BMP180 module includes an onboard voltage regulator and level shifter, making it safe to use with both 3.3V and 5V microcontrollers like the Arduino Uno.
Q: What library should I use for this sensor?
A: You can use the standard Adafruit_BMP085 library or the newer Adafruit_BMP180 library available in the Arduino Library Manager. They are fully compatible with this chip.
Q: What is the I2C address for this sensor?
A: The default I2C address for the BMP180 is 0x77. This is fixed and cannot be changed via software or hardware jumpers on this specific module.
Q: Does it come with header pins soldered?
A: No, the module typically ships with unsoldered header pins to allow for flexible mounting options. You will need to solder them yourself or use jumper wires directly.
Q: Can this measure altitude accurately?
A: Yes, by measuring atmospheric pressure, the sensor can calculate altitude relative to sea level. Accuracy depends on having a known reference pressure for your location.
