Adafruit BME280 I2C or SPI Temperature Humidity Pressure Sensor

Adafruit BME280 I2C or SPI Temperature Humidity Pressure Sensor

Regular price $0.00 $27.90 Sale

Key Features:

  • BME280: an environmental sensor with temperature, barometric pressure
  • Great for all sorts of weather sensing and can even be used in both I2C and SPI!
  • Low altitude noise of 0.25m and the same fast conversion time compared to BMP085/BMP180/BMP183

This precision sensor from Bosch is the best low-cost sensing solution for measuring humidity with ±3% accuracy, barometric pressure with ±1 hPa absolute accuraccy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter or better accuracy!

The BME280 is the next-generation of sensors from Bosch, and is the upgrade to the BMP085/BMP180/BMP183 - with a low altitude noise of 0.25m and the same fast conversion time. It has the same specifications, but can use either I2C or SPI. For simple easy wiring, go with I2C. If you want to connect a bunch of sensors without worrying about I2C address collisions, go with SPI.

Nice sensor right? The surface-mount sensor is soldered onto a PCB and comes with a 3.3V regulator and level shifting so you can use it with a 3V or 5V logic microcontroller without worry.
