BME 280 Temp Humidity Pressure
With the BME280 it is capable of communicating either through I2C and SPI. I decided to connect it with I2C since we already have multiple I2C devices connected in parallel. Here is how your setup should look like with the BMP280 connected. Note that we would only need to connect 5V/VCC, GND, SCL, and SDA for I2C. The 3Vo, SDO, and CS pins are left unconnected since we are not communicating through SPI.
I followed the Adafruit repository to closely to get the sensor to begin reading, specifically using the BME280 library and the example script.
