Humidity, Pressure, Temperature 0 ~ 100% RH I²C, SPI ±3% 1 s Surface Mount
BME280 I2C breakout module
The BME280 integrates three sensors—temperature, relative humidity, and pressure—along with a high-performance digital interface. It communicates via I²C or SPI, making it easy to interface with microcontrollers like Arduino, ESP32, and STM32.
It is designed for low power consumption, making it suitable for battery-powered applications such as portable weather stations and smart home devices.
