Abstract

PURPOSE: To facilitate the setting of detection sensitivity.
CONSTITUTION: The output voltage of a sensor 1 employing a semiconductor is compared with plural kind of reference voltages. When the output voltage of the sensor exceeds the standard value, a voltage comparator 9 is actuated to indicate changes in the output voltage of the sensor 1 by a symbol for the number of indication lamps or the like while providing a ventilation control output 12 at a set display point.
