Barometric Pressure & Altitude Sensor BMP280 I2C or SPI

Years ago, it may sound too far-fetched to say that a single tiny module can run almost all readings on a DIY weather station, but now, it isn't, thanks to this sensor from Bosch. This Barometric Pressure and Altitude sensor module is based on the new BMP280 sensor, an environmental sensor measuring the temperature, barometric pressure, and altitude - all in one tiny package. It has a ±1 hPa absolute accuracy for barometric pressure, ±1 meter accuracy for altitude, and ±1.0°C accuracy with temperature. Most notably, the module can use either I2C or SPI so that you can get the advantages of both worlds. If you prefer using fewer wires, use I2C. If you want reaction speed, use SPI. It can even use both popular logic levels 3.3V and 5V. The BMP280 module is an excellent module for environment sensing projects. Grab one while stocks last!
