Next-Generation Environmental Sensing for Your Projects
Whether you are engineering a custom flight controller for a drone or building a smart home weather station, accurate environmental data is critical. The GY-BMP280-5V Sensor Module is a robust, low-power solution that measures barometric pressure and ambient temperature with exceptional precision.
Built around the industry-standard 280-series architecture, this module acts as a highly reliable altimeter, capable of tracking elevation changes with an accuracy of up to ±1 meter.
Seamless 5V Microcontroller Integration
Forget the hassle of external logic level converters. Unlike standard 3.3V sensors, the GY-BMP280-5V features an onboard voltage regulator. This allows you to connect it directly to 5V microcontrollers like the Arduino Uno or Mega. Simply plug it into your breadboard, connect the power, and you are ready to code.
Streamlined I2C Communication
Save your valuable microcontroller pins for other components. This module utilizes a standard I2C interface (SDA/SCL), requiring only two data wires to communicate. The purple PCB clearly labels all pinouts (VIN, GND, SCL, SDA), ensuring a frustration-free wiring experience for both beginners and seasoned engineers.
Ultra-Low Power for Battery-Operated IoT
Designing a remote weather node? The GY-BMP280-5V is optimized for energy efficiency. Its ultra-low current consumption ensures that your battery-powered IoT devices and wearable tech run longer without sacrificing data accuracy or polling rates.
