Can be independently enabled / disabled, which can measure not only the temperature, but also the pressure. The BMP280 sensor is great for all sorts of weather sensing and can even be used in both and SPI. for measuring barometric pressure with +/-1 absolute accuraccy, and temperature with +/-1.0 Celsius accuracy. Because pressure changes with altitude, and the pressure measurements are good, you can also use it as an altimeter with +/-1 meter accuracy., Manufacturer: Jnchdghwa
