The SparkFun ENS160/BME280 Environmental Combo Breakout takes care of all your atmospheric-quality sensing needs with the popular ENS160 and BME280 ICs. This unique breakout provides various environmental data, including AQI, TVOCs, equivalent CO2 (or eCO2) levels, barometric pressure, humidity, and temperature. To make it even easier to use this breakout, all communication is enacted exclusively via I2C, utilizing our handy Qwiic system. However, if you prefer a breadboard, we still have broken-out 0.1in. spaced pins.
The ENS160 is the replacement for the popular CCS811 sensor, providing readings for equivalent CO2 (or eCO2) in the parts per million (PPM) and total volatile organic compounds in the parts per billion (PPB). The sensor can also provide the Air Quality Index (AQI). The ENS160 also has a feature that allows it to fine-tune its readings if it can access the current humidity and temperature. Luckily, the BME280 provides humidity, temperature, and barometric pressure! This allows the sensors to work together to give us more accurate readings than they’d be able to provide.
Add the Environmental Combo Breakout to your next project for building automation, smart home, HVAC, indoor/outdoor navigation, weather forecasting, and even personal health and wellness monitoring!
Note: The I2C address of the Environmental Combo Breakout is 0x53 / 0x77 and is jumper selectable to 0x52 / 0x76. A multiplexer/Mux is required to communicate to multiple Environmental Combo Breakout sensors on a single bus. If you need to use more than one Environmental Combo Breakout sensor, consider using the Qwiic Mux Breakout.
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Results are good. Still need to see if I can get a calibration source, but one thing to note from my comment is the need for forced air cooling over the board, otherwise you'll end up with a temperature offset from the heating sources.

The ENS160 has an internal heater which causes an approximately 7 degree F increase in the temperature read by the BME280. A fan blowing on the chips would be required to use both the sensors accurately at the same time. If the board were respun, separating the chips a little more might help.
I don't have a way to qualify the TVOC and eCO2 values, but the temperature, relative humidity, and air pressure readings while the ENS160 was in sleep were spot on.
I'll probably purchase a breakout for one or the other to add to my setup, but it would have been better to just buy the individual breakout boards.

Bought an Arduino R4 with the Qwiic system but unfortunately the R4 is not working so I can't tell you how this board is working. This review was solicited by SparkFun. Just being honest here.
