This super handy mini C02 reader can be powered by a mini USB cord which can be plugged into a phone charger (not included)
or can be powered by 2x AAA batteries - NOTE - the reader works better when powered by a 5V plug.
The reader is super compact, fits in the palm of your hand.
The unit is designed to be placed within the environment during light on, to gain a super fast and accurate reading
of C02 levels, as well as temperature and humidity!!
The unit can display both Farenheit and Celsius.
This controller does not control any devices or has any conectivity,
its just a super simple reader, that wont cost you an arm and a leg!
