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.

Details

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.
