The invention relates to indoor air environment monitoring equipment. The indoor air environment monitoring equipment is characterized in that a detection air channel is arranged in the housing of an all-in-one machine; the upper end of the detection air channel is communicated with the outside through an air-out structure; the lower end of the detection air channel is communicated with the outside through an air-in structure; a sensor group is arranged in the detection air channel and is used for detecting the flowed air flow; and the sensor group controls a circuit board to connect an output device so as to output and feed back the detection information of the air flow to a user. Through above setting, a flowing detection air flow can be formed in the detection air channel and each parameter of the detection air flow can be detected through the sensor group, so that the indoor air environment monitoring equipment can realize overall detection of the air quality. And at the same time, the indoor air environment monitoring equipment is simple in structure and has significant effect, and is suitable for popularization and usage.
