Good accuracy for altitude projects
Used this for a DIY drone altimeter. It provides stable data, though you need to calibrate it for your specific location's sea level pressure. Easy to solder onto a custom PCB.

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. Great value for the price.

Solid performance
We bought ten of these for our workshop. Nine worked immediately; one had a slightly loose pin but was easily fixed. Overall, a reliable batch for educational use.

Great for learning I2C protocols
Bought this for a university project. The documentation online is plentiful, making it very easy to get started. The sensor responds quickly to changes in pressure.

Low power consumption
Ideal for battery-powered ESP32 projects. The sleep mode features help extend battery life significantly while still logging atmospheric data every hour.

Reliable and compact
Small form factor fits perfectly inside my weatherproof enclosure. Temperature readings are surprisingly accurate when kept out of direct sunlight.
Q: What is the accuracy of the altitude measurement?
A: The sensor can detect altitude changes as small as 1 meter, but absolute altitude accuracy depends on knowing the precise local sea-level pressure at the time of measurement.
Q: Can this sensor be used underwater?
A: No, this is a barometric pressure sensor designed for air. It is not waterproof and will be damaged if submerged in liquid.
Q: Which library should I use 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 direct control.
Q: Does the package include header pins?
A: Yes, the module comes with a set of male header pins that you can solder onto the board yourself, allowing for easy breadboard usage.
Q: Is this compatible with 5V logic levels without a level shifter?
A: Yes, the GY-68 module typically includes voltage regulation and level shifting circuitry, making it safe to connect directly to 5V microcontrollers like the Arduino Uno.
