ンサの検出レベル設定回路。 In devices that use a thermistor to compensate for the off-level temperature of the CO sensor, multiple comparators are provided to set the detection level of the CO sensor based on the magnitude relationship between the thermistor output and each reference voltage, and the temperature characteristics of the CO sensor are The reference voltage input terminal and the thermistor output input terminal of a comparator that sets a detection level corresponding to a temperature range in which the temperature is reversed are in reverse phase with those of a comparator that sets a detection level corresponding to another temperature range. CO sensor detection level setting circuit.
