Description
BMP280 High Precision Barometric Pressure/Temperature/Altitude sensor Arduino Compatible Advanced Replacement of BMP180
BMP280 sensor, an environmental sensor with temperature, barometric 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 l2C and SPI!
This precision sensor 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.
