Good accuracy, easy to integrate
Used this for a small drone altimeter. It provides smooth data output. The only minor issue was that the pin headers were not pre-soldered, but that's expected at this price point.

Compact and reliable
The small form factor fits perfectly into our robot chassis. We are using it for floor detection via pressure changes, and it responds quickly to elevation shifts.

Perfect for my weather station project
This sensor module works flawlessly with my Arduino setup. The I2C communication is stable, and the pressure readings are consistent with local weather reports. Highly recommended for hobbyists.

Excellent library support
Found plenty of libraries for ESP32 and Raspberry Pi. Getting up and running took less than 10 minutes. The temperature compensation seems very accurate as well.

Great for classroom experiments
Bought five of these for our physics class to demonstrate atmospheric pressure changes. They are robust enough for student handling and provide clear data for graphing.

Solid performance for the price
Works well in my smart home hub. Occasionally needs a reset if the bus gets locked up, but overall it's a reliable component for monitoring indoor air pressure trends.
Q: Can I use this sensor underwater?
A: No, this module is not waterproof or water-resistant. It is designed for atmospheric air pressure measurement only and will be damaged if submerged.
Q: Does this come with example code for Raspberry Pi?
A: We do not include physical code media, but we provide a link in the product description to a GitHub repository with Python and C++ examples for Raspberry Pi and Arduino.
Q: How do I calibrate the altitude reading?
A: Altitude is calculated based on sea-level pressure. You must input the current local sea-level pressure (QNH) from a reliable weather source into your code to get accurate altitude results.
Q: What is the difference between the BME280 and BMP280 versions listed?
A: The BME280 measures pressure, temperature, and humidity, while the BMP280 only measures pressure and temperature. Please select the specific chip variant you need before ordering.
Q: Is this module compatible with 5V Arduino boards?
A: Yes, the module includes a voltage regulator and level shifter, making it safe to use with both 3.3V and 5V microcontrollers like the Arduino Uno.
