[0002] At present, indoor air monitoring equipment can monitor PM2.5 values, air humidity, formaldehyde and other harmful gases at the same time based on the Internet of Things. Its installation methods can be divided into floor-standing, handheld, and ceiling-wall types. The most widely used type on the market is the ceiling-wall type. The ceiling-wall type air monitoring equipment has the advantage of saving space. Its installation method is: first insert a fluffy bolt sleeve into the top of the wall to fix the fixing base on the top of the wall, and then use multiple bolts to fix the monitor to the fixing base, or fix it to the fixing base by snap-on clamping.
