摘要： PROBLEM TO BE SOLVED: To provide a gas detector not only preventing a problem in carbon monoxide detection performance even if the low temperature period of a heater is shortened, but also improving the detection performance, resultantly suppressing average power consumption, and improving the detection performance.
SOLUTION: This gas detector is equipped with the function of causing the temperature of a gas sensor body to repeat high temperature periods and low temperature periods by controlling the heater for heating the sensor body comprising a metal oxide layer and a catalyst layer and issuing an alarm if carbon monoxide exceeding a prescribed concentration reaches the sensor body at least during the low temperature period T5. Silicon dioxide SiO
2 concentration in the catalyst later is 5 wt % or less. A period T4 during which the heater is kept off is inserted between the high and low temperature periods, or a period T4 during which temperatures run lower than the temperature in the low temperature periods is inserted between the high and low temperature periods. This period T4 is 1.5 to 500 sec and the low temperature period T5 is 0.03 to 10 sec.

摘要： PROBLEM TO BE SOLVED: To provide a gas detection method to hardly generate an erroneous notification caused by gas, even when dimethyl ether contained in an insecticide or the like of a smoking type stays in a room for a long period. SOLUTION: This method includes the following processes 1-5. (1) An R1 value, an R2 value and a correction value K are determined as follows. R1: an alarming level resistance value of a gas sensor main body when a concentration of the detection objective gas reaches a concentration to issue an alarm. R2: a correction determination reference resistance value for preventing the erroneous notification from being issued by miscellaneous gases other than the erroneous notification. K: a correction value for preventing the erroneous notification from being issued, by a change in a sensor signal of the gas sensor main body with the presence of the miscellaneous gases to be judged as if exceeding the R1 value, irrespective of not reaching the concentration of the detection objective gas to issue the alarm. (2) A resistance value R3 of the gas sensor main body is measured just after switched from a low temperature period to a high temperature period. (3) The R1 is multiplied by the correction value K to bring the R1 into a corrected resistance value R1' in a measured value R2>R3. (4) A resistance value R4 of the gas sensor main body is measured in the high temperature period. (5) The alarm is not issued in the case of R4>R1' after the measured value R4 obtained in the (4) is compared with the corrected resistance value R1'. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a gas detector in which the detection accuracy of a detection object gas is less likely to deteriorate even in a case where a gas sensor has large temperature dependency.SOLUTION: A storage unit 38 preliminarily stores a resistance value of a gas sensor 2 associated with humidity in standard atmosphere, as known data. A detection processing unit 35 includes a calculation section 351 for acquiring a correction value corresponding to humidity in atmosphere, and a correction section 352 for correcting a detection result of a detection object gas by using the correction value. In an inflow path of the detection object gas to the gas sensor 2, a filter is provided so that the reaction rate of the gas sensor 2 with respect to the humidity is made slower than the reaction rate of the gas sensor 2 with respect to the detection object gas. When variation per unit time of the resistance value of the gas sensor 2 becomes less than a determination threshold, the calculation section 351 calculates the correction value from the current resistance value of the gas sensor 2 and the know data in the storage unit 38.
