Abstract
The utility model provides an intelligent sensor tester of a gas alarm. As the characteristic shown when the sensor detects the harmful gas is the impedance characteristic, the concentration of the gas can be analyzed according to the impedance characteristic; and when the concentration of the gas reaches a critical point and the gas is harm to the life and property, a single chip microcomputer is used for controlling a circuit to alarm. The intelligent tester comprises a singlechip (1), wherein one end of the singlechip is connected with a resetting and clock circuit (2), the other end of the singlechip is connected with a sensor data acquirer (3), the upper end of the singlechip is connected with a nixie tube displayer (4), and the lower end of the singlechip is connected with a power interface (5). The intelligent tester is used for gas alarm.
