BME280 Temperature, Humidity & Pressure Sensor (I²C/SPI)

The Bosch BME280 combines three precise sensors: temperature (±1 °C), humidity (±3 % RH) and barometric pressure (±1 hPa), which also gives altitude to about ±1 m. It talks I²C or SPI and is supported by every major platform, from Arduino and ESP32 to ESPHome and Raspberry Pi.

Key features

• Temperature, humidity and pressure in one sensor
• Pressure accuracy ±1 hPa — altitude resolution around 1 m
• I²C (0x76/0x77) or SPI interface
• Very low power — ideal for battery weather nodes
