The mems based wireless carbon dioxide sensor allows you to monitor the level of carbon dioxide (CO2) gas in the surrounding air. Monnit wireless CO2 sensors have a small footprint and low cost but boast industry leading, premium performance specifications and are the longest lifetime sensors in the industry and the only CO2 sensor on the market powered by a coin cell battery (battery lasts over a year at 1 hour heartbeat). User customization allows you to set the frequency of readings and the ability to set customized alerts via SMS text or email when the sensor detects CO2 levels outside of the user's defined safe levels.
