BMP280 Stainless Steel Probe Wire 1 Meter - I2C Digital Output

The integrated 4-wire cable uses a standard I2C color code: Red for VCC (3.3V-5V), Black for Ground (GND), Yellow for Serial Data (SDA), and Green for Serial Clock (SCL). Simply connect these to the corresponding pins on your microcontroller's I2C bus, ensuring you include pull-up resistors on the SDA and SCL lines if not already present on your board.

Yes, the BMP280 probe is fully compatible with both 3.3V and 5V logic levels. You can connect the Red VCC wire to either a 3.3V or 5V output pin on an Arduino, Raspberry Pi, or other development board. The sensor's internal regulator and I2C interface are designed to operate across this entire voltage range without damage.

The stainless steel housing provides robust protection against physical damage, moisture, and dust, making it suitable for demanding environments. However, for fully submerged or high-pressure water jet applications, additional sealing at the cable entry point is recommended to ensure complete waterproofing.

For Arduino, the most common and well-supported library is the Adafruit BMP280 Library. It provides easy-to-use functions for initializing the sensor and reading calibrated pressure and temperature values. Ensure your sketch includes the Wire.h library for I2C communication and configures the correct I2C address (typically 0x76 or 0x77).
