The BME280 sensor is a precision sensor, is soldered onto PCB, not only the pressure and the temperature, this sensor can measure humidity..
BME280 5V uses both I2C and SPI (supports 3-, 4-wire SPI) interface. Interface: I2C (up to 3.4MHz).
Temperature humidity module is great for all sorts of weather sensing and can even be used in both I2C and SPI. for simple easy wiring, go with I2C. If you want to connect a bunch of sensors without worrying about I2C address collisions, go with SPI..
The BME280 stmospheric pressure sensor is made up of a very accurate pressure sensor and an associated temperature sensor which helps calibrate the pressure readings..
The BME280 sensor is 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 good, you can also use it as an altimeter with ±1 meter accuracy..
