CCS811 Air Quality Sensor Breakout Board

SKU 58914193

The CCS811 Air Quality Breakout board from PMD Way uses a digital gas sensor solution which allows your project to senses a wide range of Total Volatile Organic Compounds (TVOCs) - including equivalent carbon dioxide (eCO2) and metal oxide (MOX) levels. 

Free delivery, worldwide.

VOCs are often categorized as pollutants and/or sensory irritants and can come from a variety of sources like construction materials (paint, carpet, etc.), machines (copiers, processors, etc.) and even people (breathing, smoking, etc.). This breakout is intended for indoor air quality monitoring in personal devices such as watches and phones, but we’ve put it on a breakout board so you can use it as a regular I2C device.

The onboard CCS811 supports multiple measurement modes that have been optimised for low-power consumption during an active sensor measurement and idle mode extending battery life in portable applications. Header pins are included but not soldered to the board.

Note: Please be aware that the CCS811 datasheet recommends a burn-in of 48 hours and a run-in of 20 minutes (you must allow 20 minutes for the sensor to warm up and output valid data).

This board is based on Sparkfun's SEN-14193 which is an open-hardware design. 

We also offer a board that includes both the CCS811 and the HDC1080 temperature/humidity sensor.
