This BMP280 is a cheapest and tiny Atmospheric Sensor Breakout to measure barometric pressure, and temperature readings all without taking up too much space. Basically, because anything you need to know about atmospheric conditions you can find out from this tiny breakout. The BMP280 Breakout has been design to be used in indoor/outdoor navigation, weather forecasting, home automation, and even personal health and wellness monitoring.
This module uses an environmental sensor manufactured by Bosch with temperature and barometric pressure sensor that is the next generation upgrade to the popular BMP085/BMP180/BMP183 Sensor. So, this sensor is great for all sorts of weather sensing and can even be used in both I2C and SPI! and this precision sensor from Bosch is the best low-cost, precision sensing solution for measuring barometric pressure with ±1 hPa absolute accuraccy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, so you can also use it as an altimeter with ±1 meter accuracy.
So,the BMP280 is the next-generation of sensors, and is the upgrade to the BMP085/BMP180/BMP183 with a low altitude noise of 0.25m and the same fast conversion time. Because it has the same specifications, but can use either I2C or SPI. For simple easy wiring, go with I2C. Because if you want to connect a bunch of sensors without worrying about I2C address collisions, go with SPI.
