Gas leak hunting detection device

The utility model discloses a gas leak hunting detection device. The gas leak hunting detection device comprises a single-chip microcomputer, a gas-sensitive sensor, an alarm unit, a solenoid valve driving unit, a solenoid valve, a driver and an LED display, wherein the gas-sensitive sensor is connected with an input end of the single-chip microcomputer, an output end of the single-chip microcomputer is respectively connected with the alarm unit, the driver and the solenoid valve driving unit, an output end of the driver is connected with the LED display, and the solenoid valve driving unit is connected with the solenoid valve. By utilizing the semiconductor gas-sensitive sensor, indoor gas concentration can be detected in real time through adsorption of inflammable gas in a surrounding environment, and the gas concentration is displayed through the LED display in real time; when the gas concentration in the environment reaches to a safety threshold value, acousto-optic alarm is carried out, simultaneously, t
