Feature

●GY-BME280-3.3V for the pressure , the temperature and measure humidity.
●BMP280 sensor pressure board support I2C and SPI (supports 3-, 4-wire SPI) interface, 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
●BME280 3.3v supports a full suite of operating modes which provides the flexibility to optimize the device for power consumption, resolution, and filter performance.
●Temperature humidity sensor module made of a very accurate pressure sensor and an associated temperature sensor which helps calibrate the pressure readings.
●The pressure sensor is an absolute barometric pressure sensor which features exceptionally high accuracy and resolution at very low noise, you have access to enough weather data to make some pretty good predictions for your local area.
