The BMP280 is a compact barometric pressure and temperature sensor module for Arduino, ESP32, Raspberry Pi, and other microcontroller projects. It is ideal for weather stations, altitude measurement, drones, environmental monitoring, and data logging.
- Measures barometric pressure and temperature
- Supports both I2C and SPI communication
- Compact GY-BM280 breakout module
- Great for Arduino, ESP32, Raspberry Pi, and STM32 projects
- Perfect for weather, altitude, and environmental sensing
Quick Start
1
Connect power
Connect VCC to 3.3V and GND to GND.
2
Connect I2C pins
Connect SCL to A5/SCL and SDA to A4/SDA on an Arduino Uno.
3
Install library
Use the Adafruit BMP280 library or another compatible BMP280 Arduino library.
4
Check address
Default I2C address is usually 0x76. Pull SDO high to use 0x77.
Please note: This is the BMP280 version. It measures pressure and temperature only, not humidity.

Getting Started
1
Wire VCC and GND
Connect VCC to 3.3V and GND to GND.
2
Wire I2C
For Arduino Uno, connect SCL to A5 and SDA to A4.
3
Leave CSB and SDO unconnected
This keeps the module in default I2C mode with address 0x76.
4
Install a BMP280 library
Install the Adafruit BMP280 library through the Arduino Library Manager.
5
Upload example sketch
Open a BMP280 example sketch, select your board and port, then upload.
Wiring: VCC → 3.3V, GND → GND, SCL → A5/SCL, SDA → A4/SDA.

Common Questions
Is this a BMP280 or BME280?
This is a BMP280. It measures pressure and temperature only. It does not measure humidity.
Can I use this with Arduino?
Yes, it works with Arduino boards using I2C or SPI. For Arduino Uno I2C, use SDA on A4 and SCL on A5.
Can I use this with ESP32 or Raspberry Pi?
Yes, it is compatible with ESP32, Raspberry Pi, STM32, and other 3.3V microcontroller platforms.
Can I connect it to 5V?
This is a 3.3V module. Do not connect directly to 5V unless using proper voltage level shifting.
Please note: If your code cannot find the sensor, check the I2C address. It may be 0x76 or 0x77.
