BMP280 BMP-280 I2C SPI

High Precision Temperature & Air Pressure Sensor module


Bosch has stepped up their game with their new BMP280 sensor, an environmental sensor

with temperature, barometric air pressure that is the next generation upgrade to the BMP085/BMP180/BMP183.

This sensor is great for all sorts of weather sensing and can even be used in both I2C and SPI

This precision sensor from Bosch is the best low-cost, precision sensing solution for measuring

barometric pressure with ±1 hPa absolute accuracy, 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 accuracy.


Works with Adafruit BMP280 Library, initialise it with:

    bmp.begin(0x76)
