SparkFun Environmental Combo Breakout - ENS160/BME280 (Qwiic)

The SparkFun ENS160/BME280 Environmental Combo Breakout is a comprehensive atmospheric quality sensor, combining the capabilities of the ENS160 and BME280 ICs. This breakout can provide a wide array of environmental data such as Air Quality Index (AQI), Total Volatile Organic Compounds (TVOCs), equivalent CO₂ (eCO₂) levels, barometric pressure, humidity, and temperature. All communication is carried out via I²C, using the Qwiic system for ease of use. For those who prefer a breadboard setup, 2.54mm spaced pins are available.

The ENS160 sensor, an upgrade from the popular CCS811 sensor, can provide readings for eCO₂ in parts per million (PPM) and TVOCs in parts per billion (PPB), as well as the AQI. It can fine-tune its readings when given access to current humidity and temperature data. This is where the BME280 comes in, providing humidity, temperature, and barometric pressure data, allowing the sensors to work together for more accurate readings.

The Environmental Combo Breakout can be a valuable addition to a variety of projects, including building automation, smart home systems, HVAC, indoor/outdoor navigation, weather forecasting, and personal health and wellness monitoring.

The I²C address of the Environmental Combo Breakout is 0x53 / 0x77 and can be selected to 0x52 / 0x76. A multiplexer/Mux is required to communicate with multiple Environmental Combo Breakout sensors on a single bus. If you plan to use more than one Environmental Combo Breakout sensor, consider using a Qwiic Mux Breakout.

The SparkFun Qwiic Connect System is a hassle-free ecosystem of I²C sensors, actuators, shields, and cables that makes prototyping faster and less prone to errors. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector, reducing the amount of required PCB space. The polarized connections ensure correct hook-up.

Features of the SparkFun ENS160/BME280 Environmental Combo Breakout include 2x Qwiic-Enabled Connectors, input voltage range typically 3.3V via Qwiic cable, ENS160 and BME280 sensors with wide operating ranges and various reading capabilities, power LED, 1.8V AP2127K Voltage Regulator (for ENS160), 2.2kΩ Pull-up Resistors, selectable addresses, board dimensions of 25.4mm x 25.4mm, and a weight of 2.50g.
