The utility model is characterized in that: one CO 2 sensor is used, and at least one electromagnetic valve is used. One electromagnetic valve controls the opening and closing of air of a mushroom room to be tested, and the plurality of electromagnetic valves share a gas filter, and the gas filter is connected to the exhaust fan in turn. The CO 2 sensor, CO 2 sensor output signal is sent to the control system after being processed by the PLC, and the CO 2 concentration is displayed on the display in numerical form. When the equipment is used for the mushroom house, each mushroom room is equipped with a solenoid valve to the outdoor pipe, and a plurality of solenoid valves share a gas filter.
