/* Ex1_Combined_Basic_Example_ENS160_BME280.ino

This example shows basic data retrieval from the SparkFun Environmental Combo Breakout
from the Air Quality Sensor (ENS160) and Atmospheric Sensor (BME280).

This example shows how to read sensor readings from the ENS160 (air quality index tVOC, and eCO2)
and BME280 (humidity, pressure, and current temperature) over I2C.
