Summary:The utility model discloses an automobile air pressure electronic monitoring device which comprises an air pressure sensor, a battery, a sound warning chip, a bulb, a first resistor, a second resistor, a triode, an inductor and a loudspeaker. The air pressure sensor is connected when sensing that the air pressure of an automobile tire is low, at the time the bulb is lighted up and emits light to give an alarm, and a sound integrated chip is triggered to be started, so that the triode triggers the loudspeaker to give an audible alarm. Compared with the prior art, the automobile air pressure electronic monitoring device is installed on a wheel valve of an automobile through the air pressure sensor; when the air pressure is insufficient, an sound-light alarm is given to remind drivers of supplementing wheel air pressure, so as to avoid safety accidents of an automobile in the running process, and the automobile air pressure electronic monitoring device is convenient to use and has popularizing and applying values.
