Carbon Dioxide Detector

This carbon dioxide detector measures CO2, air temperature and humidity. A useful tool to help to regulate ventilation in enclosed spaces such as classrooms, indicating when fresh air should be allowed in to help remove air that contains virus particles and to help prevent the spread of Covid-19. People exhale carbon dioxide when they breath out. If there is a build-up of this in an area it can indicate that ventilation needs improving. This device adopts a high-precision non-dispersive infrared CO2 sensor that detects CO2 accurately and sensitively. Containing a high-capacity rechargeable lithium battery, making it easily portable. To preserve electricity, it powers off after 30 minutes of inactivity. A USB charging cable is also provided allowing simple recharging using either a PC or mains plug.
