BME280 Temperature Humidity Pressure Sensor Module, I2C/SPI, 3.3V/5V

Overview The BME280 Environmental Sensor is a compact sensor breakout module designed for temperature, humidity and barometric pressure measurement. With the BME280 onboard, this module is suitable for environmental monitoring, pressure sensing, altitude reference, data collection, education projects and embedded development applications. This BME280 sensor module supports both I2C and SPI communication. I2C is used by default and supports configurable slave address settings, while SPI can be selected through I/O configuration. The flexible interface design helps reduce wiring difficulty and allows easy integration with different controller boards. The onboard voltage level translator supports both 3.3V and 5V operating levels, improving compatibility with common development platforms.

Development resources and example codes are available for Raspberry Pi, for Arduino and STM32, helping developers quickly test temperature, humidity and pressure sensing functions. With a small 27mm × 20mm form factor, low current consumption and stable measurement performance, this BME280 breakout is suitable for compact electronics projects, sensor nodes, weather data collection, pressure reference projects, educational experiments and microcontroller-based measurement systems.
