This wall mount CO2 Controller comes with an external CO2 sensing probe that measures CO2 level in closed spaces. You can use it for CO2 monitoring in indoor air quality and greenhouse CO2 measurement. Can also be used and operated in other workspaces like offices, hospitals, schools, stations, residential, commercial buildings or home usage. 

This unit can also control other connected instruments such as CO2 generators or ventilation fans easily with two modes (the plant OR human mode) to override the controlling in low or high CO2 concentration.
