Description

The GY-BMP280-5V module integrates the Bosch BMP280, a low-power, high-precision MEMS sensor originally developed for mobile applications. It measures absolute barometric pressure from 300 hPa to 1100 hPa and ambient temperature from -40°C to +85°C with a resolution of ±1 Pa and ±1°C, respectively. The sensor’s digital output is conditioned and made accessible via standard I2C and SPI pins, allowing for seamless integration with Arduino, ESP32, STM32, and Raspberry Pi platforms.

This module is engineered for stability and low current consumption, making it suitable for battery-powered portable devices. The onboard logic level translation ensures reliable communication with both 3.3V and 5V microcontrollers. Its small form factor and robust performance make it a core component for advanced environmental sensing, drone altitude hold, and predictive weather station applications.

Key Features

  • Bosch BMP280 MEMS environmental sensor with proven accuracy and long-term stability.
  • Supports high-speed I2C (3.4 MHz) and SPI (10 MHz) communication for data-intensive applications.
  • Wide operating temperature range from -40°C to +85°C for harsh environment reliability.
  • Configurable I2C address (0x76 or 0x77) via SDO pin for bus multiplexing.
  • Ultra-compact and lightweight PCB module design for space-constrained projects.
  • Optimized for low-power operation, ideal for mobile and IoT sensor nodes.
  • Direct digital output eliminates the need for external analog signal conditioning.
  • High-value build providing laboratory-grade sensing performance at a competitive cost.

Applications

  • Drone and UAV altitude hold and barometric navigation systems.
  • Portable weather stations and personal environmental monitors.
  • Indoor floor detection and vertical velocity indication for elevator systems.
  • GPS enhancement for faster time-to-first-fix and dead reckoning in navigation devices.

Frequently Asked Questions

What is the difference between the I2C addresses 0x76 and 0x77 on this module?

The GY-BMP280 module's I2C address is selected by the state of the SDO pin. Connecting SDO to GND sets the address to 0x76, while pulling it to VCC (3.3V/5V) sets it to 0x77. This allows you to connect two identical sensors to the same I2C bus for redundant sensing or multi-point measurement setups.

Can I use this 5V-rated module with a 3.3V microcontroller like the ESP32 or Raspberry Pi?

Yes, the module is fully compatible with 3.3V logic. While the operating voltage range is 1.8V to 5V, the digital I2C and SPI lines are not strictly 5V-only. You can power it with 3.3V and connect directly to 3.3V logic GPIOs without risk of damage, ensuring reliable communication with low-voltage MCUs.

How do I read data from the sensor using the SPI interface?

To use SPI, connect the module's SCLK, SDI (MOSI), SDO (MISO), and CS pins to your microcontroller's corresponding SPI pins. The CS (Chip Select) pin must be controlled by a GPIO. Ensure your SPI library is configured for the correct mode (Mode 0 or 3) and clock speed up to 10 MHz. The SPI protocol provides faster data transfer rates compared to I2C.

What is the typical accuracy and response time for pressure measurements?

The Bosch BMP280 sensor provides an absolute accuracy of ±1 hPa and a relative accuracy of ±0.12 hPa under typical conditions. The response time for pressure measurement is very fast, typically under 1 ms. For high-precision applications, you can implement oversampling and filtering in software to reduce noise and improve the effective resolution of your readings.
