Frequently Asked Questions

What is the supply voltage range for this BMP280 module?

The module operates from 3.3V to 5V DC, making it directly compatible with most microcontroller platforms like Arduino (5V), Raspberry Pi (3.3V), and ESP32 (3.3V). Ensure your I2C logic levels match the supply voltage.

How do I connect and communicate with the sensor using I2C?

Connect the module's VCC, GND, SDA, and SCL pins to your microcontroller's corresponding I2C bus pins. The sensor has a default I2C address (0x76 or 0x77). Use standard I2C libraries to read pressure and temperature data registers.

What is the purpose of the cotton core inside the white shell?

The cotton core acts as a mechanical damper, absorbing vibrations and reducing stress on the MEMS sensor die. This improves measurement stability and accuracy, especially in mobile or high-vibration environments.

Can this sensor be used for altitude measurement?

Yes. The BMP280 provides highly accurate barometric pressure readings, which can be converted to altitude using the barometric formula. It is commonly used in drones, wearables, and weather balloons for altitude tracking.

What is the accuracy of the temperature sensor?

The integrated temperature sensor has an accuracy of ±0.5°C at 25°C. Over the full operating range (-40°C to +85°C), the absolute accuracy may vary, but it is suitable for environmental monitoring and pressure measurement compensation.
