Great for learning sensors

Bought this for a university project. The documentation online is plentiful, making it easy to get started. The size is compact and fits well on a breadboard.

Accurate barometric pressure

Compared the readings with a professional digital barometer, and the results were within 1 hPa. Excellent precision for the price point. Fast shipping too.

Good value, accurate readings

Used this for a small DIY drone altimeter. It provides consistent altitude estimates based on pressure. Just remember it needs 3.3V logic ideally, though it worked on 5V with pull-ups.

Easy to integrate

As someone new to electronics, I found this sensor very forgiving. The wiring is simple (only 4 pins), and the code examples worked immediately. Lost one star because the header pins were slightly loose.

Perfect for weather station projects

This BMP180 module works flawlessly with my Arduino Uno. The I2C communication is stable, and the library support is excellent. Reading pressure and temperature data was straightforward.

5 FAQ

Q: What is the update rate of the sensor?

A: The update rate depends on the resolution setting chosen in your code. It ranges from approximately 4.5ms for ultra-low power mode to about 25.5ms for high-resolution mode.

Q: What library should I use for this sensor?

A: The most popular library is 'Adafruit_BMP085' or 'SparkFun_BMP180', both of which are fully compatible with the BMP180 chip and available in the Arduino Library Manager.

Q: Can this measure altitude accurately?

A: It calculates altitude based on atmospheric pressure changes. While good for relative height changes (like in a drone), absolute altitude requires calibration against local sea-level pressure data.

Q: Is this module compatible with 5V Arduino boards?

A: Yes, the module includes a voltage regulator and level shifting, making it safe to use with 5V systems like the Arduino Uno, although 3.3V is preferred for optimal performance.

Q: Does this 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.
