The Wall-mounted Carbon Dioxide Sensor is a stand-alone carbon dioxide (CO₂) sensor for use in determining ventilation necessity with HVAC controllers. This sensor measures the CO₂ concentration in the ventilated space or duct. The sensor is used in ventilation and air conditioning systems to control the amount of fresh outdoor air supplied to maintain acceptable levels of CO₂ in the space.
