Thank you for purchasing the Smart Wireless Carbon Dioxide Sensor. We pride ourselves on producing high quality products that meet with the demands of the busy classroom environment. If you have any problems using this sensor, please read this documentation in full before contacting the Data Harvest support team. 


The Wireless Smart Carbon Dioxide sensor uses a pulsed infrared light source to measure the amount of carbon dioxide. Carbon dioxide is a strong absorber of infrared, so a reduction of the infrared from source to detector will be proportional to the amount of carbon dioxide present. 

The sensor is only for the measurement of carbon dioxide in dry gas environments.

The sensor is temperature compensated and can operate in high humidity environments.  

The Wireless Smart Carbon Dioxide sensor also has temperature and pressure sensors built in. 

This sensor can be used to investigate the amount of CO2 in the air and how it changes over time. A Nalgene bottle, into which it fits, is included to create a contained environment for study of plants and small animals. (NB for gaseous use only. Not for use in water).
