とするガス漏れ警報器。 A gas leak alarm using a semiconductor heated by a heater as a gas sensor includes a switching regulator 6 that controls the heater voltage of the gas sensor 3 and a switching regulator 6 that issues an alarm based on the input of the gas sensor 3. The control circuit 27 is provided with a microcomputer, for example, and controls the reference voltage of the switching regulator 6, and also checks the oscillation state of the output of the gas sensor 3, and determines whether the heater voltage is below a certain heater voltage value or A gas leak alarm is characterized by having a built-in function to notify the end of the life of the gas sensor 3 when the oscillation exceeds a certain reference value.
