Favorited Favorite 0

Hello there! It's Friday, and that means more brand new products! We are very happy to bring you two SparkFun originals that you are sure to love. We have developed a breakout surrounding the brand new CCS811 air quality sensor, as well as a more reliable passive infrared sensor that we have dubbed the OpenPIR! Let's jump in and take a closer look.

What does the VOC say?! ~sigh~ We love 4-year-old references...

SparkFun Air Quality Breakout - CCS811

9 Retired

The CCS811 Air Quality Breakout is a digital gas sensor solution that senses a wide range of Total Volatile Organic Compounds (TVOCs), including equivalent carbon dioxide (eCO2) and metal oxide (MOX) levels. 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.

SparkFun OpenPIR

SparkFun OpenPIR


The SparkFun OpenPIR is a highly customizable Passive Infrared (PIR) sensor based around the NCS36000 PIR controller. Passive Infrared (PIR) sensors are able to detect motion in a small/local area –-- they’re the sensor of choice in security systems, home automation and proximity-sensing applications. The OpenPIR allows you to set the sensitivity, trigger time and pulse mode of the motion sensor so you can tailor-fit it to your application!

That's it for this post! Be sure to check back with us next week, when we'll have something big in store that we're excited to finally reveal! See you then!
