Chattanooga, Tennessee-based company Variable, Inc. has launched and successfully funded another module for NODE, the tube-like wireless sensor platform that measures things like temperature and motion and sends the information to the user’s smart device.

The new module, NODE + CO2, uses a miniaturized Non-Dispersive Infrared (NDIR) sensor to measure the carbon dioxide levels of the air around it and sends the information to the user’s smartphone or tablet. The accompanying N+Oxa app will sync the CO2 data with the NODE Blue™ cloud server so that users can retrieve their data anywhere and anytime.


The module can do quick CO2 readings in a home, office or classroom, and the creators are working to enable the device to track CO2 levels over a period of time. They are also looking into enabling it to store CO2 data when there is no smart device in range.

The NODE + CO2 had just finished its campaign on Kickstarter and will start shipping out in April.

NODE was launched and funded on Kickstarter in March 2012. A few months later the company successfully funded its Chroma module, a color sensor that scans any color on any surface and translates the information to a color code for the user.
