Adafruit BME280 I2C or SPI Temperature Humidity Pressure Sensor - STEMMA QT

The Bosch BME280 sensor is an advanced environmental sensor that combines temperature, barometric pressure, and humidity measurements into one compact and precise package. Perfect for indoor environmental sensing, this sensor is ideal for a variety of applications and offers both I2C and SPI connectivity for flexibility in your projects.

Key Features:

• High Accuracy:
  • Humidity: ±3% accuracy
  • Barometric Pressure: ±1 hPa absolute accuracy
  • Temperature: ±1.0°C accuracy
• Altimeter Functionality: The sensor can also be used as an altimeter, offering ±1 meter or better accuracy in altitude measurements.
• Precision Measurements: The BME280 delivers superior pressure readings with a low altitude noise of just 0.25 meters, making it ideal for highly accurate environmental and altitude tracking.

Connectivity Options:

• I2C: For simple, easy wiring to microcontrollers with no fuss.
• SPI: Perfect for connecting multiple sensors without worrying about address conflicts.

Easy Integration:

The sensor comes pre-soldered onto a custom PCB and features a 3.3V regulator and level shifting, making it compatible with both 3V and 5V logic microcontrollers. The breakout board uses the STEMMA QT form factor, which makes interfacing with the sensor simple and easy. It also supports SparkFun's Qwiic I2C connectors, allowing for solderless connections to your development board and making it easier to chain multiple sensors together.
