The invention relates to the technical field of monitoring environmental temperature and humidity, and discloses an air humidity measuring device. The air humidity measuring device comprises a protective cover, a dry bulb thermometer, a wet bulb thermometer, a blower, a processor and a CO2 sensor, wherein the dry bulb thermometer, the wet bulb thermometer and the blower are arranged inside the protective cover, and the processor and the CO2 sensor are arranged outside the protective cover; a fabric soaked with water is wrapped on a thermometer bulb of the wet bulb thermometer, and the lower end of the fabric is soaked in a water containing bottle containing water; the blower is arranged corresponding to the dry bulb thermometer and the wet bulb thermometer; and the dry bulb thermometer, the wet bulb thermometer, the blower and the CO2 sensor are connected with the processor respectively. According to the air humidity measuring device provided by the invention, the protective cover is used, so that the phenomenon of condensation is reduced, and the influence of the condensation on measurement is also reduced; an air humidity sensor is improved by adopting a dry-wet bulb measuring method, so that the measurement accuracy of the air humidity is improved; and meanwhile, the blower is arranged inside the sensor according to the design of the air humidity measuring device provided by the invention to enhance ventilation, thereby ensuring the measurement accuracy.
