Bulk buy success
Bought ten of these for our workshop. All units tested functional out of the box. Consistent performance across all modules makes teaching much easier.

Reliable barometric data
I have been logging data for two weeks straight. The temperature compensation seems accurate, and the pressure trends match local weather reports perfectly.

Good accuracy for the price
Used this for altitude hold on a small quadcopter. It responds quickly to pressure changes. Just make sure you use the correct voltage regulator if running at 5V logic.

Perfect upgrade from my old BMP085
This sensor works flawlessly with my Arduino Uno. The library support is excellent, and the readings are very stable compared to my older module. Great for weather station projects.

Easy to integrate
As a beginner, I found the wiring diagram easy to follow. The I2C address was detected immediately. Highly recommend for school science projects involving atmospheric data.

Low power consumption confirmed
Great for battery-powered nodes. The sleep mode works as advertised. Only giving 4 stars because the soldering pads are a bit small for thick wires.
Q: What is the default I2C address for this sensor?
A: The default I2C address for the BMP180 is typically 0x77. You can verify this using an I2C scanner sketch.
Q: Is this module compatible with 5V Arduino boards without a level shifter?
A: Yes, the GY-68 board includes a voltage regulator and level shifting circuitry, making it safe to use directly with 5V logic boards like the Arduino Uno.
Q: Which library do you recommend for Python on Raspberry Pi?
A: We recommend using the 'Adafruit_CircuitPython_BMP180' library or the standard 'smbus' library with the datasheet register map for custom implementations.
Q: Can this measure altitude accurately indoors?
A: While it can detect relative height changes, indoor air pressure fluctuations caused by HVAC systems or opening doors may affect absolute altitude accuracy. It is best calibrated against a known reference point.
Q: Does the package include connecting wires?
A: No, the package contains only the sensor module. You will need to purchase jumper wires separately to connect it to your microcontroller.
