The BMP280 sensor is great for all sorts of weather sensing and can even be used in both and SPI. Can be independently enabled / disabled, which can measure not only the temperature, but also the pressure. 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., Weight: 0.01322773572 Pounds, Manufacturer: Histeaa
