Unpacking the Gy Bmp280 33 Datasheet: What It Tells You
The Gy Bmp280 33 Datasheet is more than just a dry technical document; it’s a roadmap for integrating the BME280 sensor into your projects. It specifies the sensor’s operating voltage (typically 3.3V, hence the “33” in the name), which is critical for preventing damage. It also defines the communication protocols, most commonly I2C or SPI, enabling microcontrollers like Arduinos or Raspberry Pis to interact with the sensor. Understanding these details is crucial for ensuring reliable and accurate data readings. Beyond basic connectivity, the datasheet outlines the sensor’s performance characteristics. This includes:
- Temperature measurement range and accuracy.
- Pressure measurement range and accuracy.
- Power consumption in different operating modes.
- Noise characteristics.
These specifications help you determine if the sensor is suitable for your application and how to calibrate it for optimal performance. For example, high-altitude applications might require careful consideration of the pressure measurement range. The datasheet also provides information about the physical dimensions of the GY-BMP280-3.3 module and the pinout diagram. Here is an example table on the possible pinout:
| Pin | Description |
|---|---|
| VIN | Power supply (3.3V) |
| GND | Ground |
| SCL | I2C Clock |
| SDA | I2C Data |
| This enables you to easily connect the sensor to your microcontroller or other electronic components. Without this information, you’d be left guessing about the correct connections, potentially damaging the sensor or your development board. So, in short, the Gy Bmp280 33 Datasheet is important because it tells you how to safely and correctly use the sensor. To get the most out of your GY-BMP280-3.3 module, it’s highly recommended that you consult the official BME280 datasheet from Bosch Sensortec, as well as the documentation specific to the GY-BMP280-3.3 breakout board. These sources will provide the most accurate and comprehensive information. |
