A combined air quality and environmental sensor breakout featuring the ENS160 (air quality index, eCO2, TVOCs) and BME280 (temperature, humidity, barometric pressure) on a single Qwiic-enabled board. The two sensors work together — the BME280 provides real-time humidity and temperature data that the ENS160 uses to fine-tune its air quality readings for greater accuracy.
All communication is via I²C with Qwiic connectors for solderless setup. Standard 0.1″ headers are also broken out for breadboard use. Jumper-selectable I²C addresses allow flexibility in multi-sensor configurations.
Key Features
- ENS160 Air Quality Sensor – AQI (1–5), eCO2 (400–65,000 ppm), TVOC (0–65,000 ppb)
- BME280 Environmental Sensor – Temperature, humidity, and barometric pressure
- Sensor Fusion – BME280 data improves ENS160 accuracy
- Qwiic / I²C Interface – 2× Qwiic connectors, no soldering required
- Jumper-Selectable Addresses – ENS160: 0x53/0x52, BME280: 0x77/0x76
- CCS811 Replacement – ENS160 is the next-generation air quality sensor

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- ppm
- ppm means parts per million, a common way to express very small gas concentrations in air. For CO₂ sensors, the ppm range tells you what levels the sensor can measure, such as normal indoor air through to poorly ventilated spaces.
- Qwiic
- Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
- UPS
- An uninterruptible power supply is a battery-backed power system that keeps a device running when external power is unplugged or fails. For an embedded computer, it helps prevent sudden shutdowns that can corrupt files or interrupt a project.
