GY-BME280 3.3V 5V BMP280 Digital Sensor Temperature Barometric Air High Precision Atmospheric Pressure Module I2C SPI For Arduin

The GY-BME280 Digital Sensor Module is a high-precision environmental monitoring component compatible with 3.3V and 5V power supplies, designed specifically for Arduino projects and other microcontroller platforms. Based on Bosch’s advanced BME280 and BMP280 chips, this module integrates temperature and atmospheric pressure detection functions, with the BME280 variant additionally supporting humidity measurement, making it a versatile solution for various environmental sensing applications. Equipped with dual communication interfaces—I2C (Inter-Integrated Circuit) and SPI (Serial Peripheral Interface)—the module offers flexible connection options, ensuring seamless compatibility with a wide range of Arduino models, including Uno, Nano, Mega, and Leonardo, as well as other controllers like ESP32 and Raspberry Pi. This dual-interface design allows it to adapt to different project wiring needs, whether for space-constrained setups or high-speed data transmission requirements. Boasting high precision, the module delivers accurate measurements across a wide range: temperature ranges from -40°C to +85°C with an accuracy of ±1°C, atmospheric pressure ranges from 300 to 1100 hPa (corresponding to an altitude of -500m to 9000m) with a precision of ±1 hPa, and the BME280 variant measures humidity from 0 to 100% RH with ±3% RH accuracy. Its low power consumption design (as low as 0.1μA in sleep mode) makes it ideal for battery-powered and long-term monitoring projects such as portable weather stations and IoT data logging systems. The module features a compact and durable design, with a small form factor (approximately 15mm × 12mm) that facilitates easy integration into various projects, from hobbyist experiments to industrial applications. It requires no complex wiring or external clock circuits, and comes with built-in voltage regulation and logic level shifters, supporting both 3.3V and 5V power supplies to avoid damage to the module when connected to different Arduino power outputs. Suitable for a wide range of applications, including weather stations, smart home automation, drone altitude measurement, indoor air quality monitoring, and educational projects, this GY-BME280/BMP280 module is a practical and cost-effective choice for extending environmental sensing capabilities to your Arduino system. It is compatible with popular Arduino libraries (such as Adafruit BME280 and GyverBME280), enabling beginners and experienced enthusiasts alike to quickly implement data collection and analysis功能.
