Air humidity monitoring instrument for environmental monitoring

An air humidity monitoring instrument for environmental monitoring disclosed by the present invention comprises a fixed column, a supporting column is arranged in the fixed column, a lifting mechanism cooperatively used with the supporting column is arranged in the fixed column, a mounting rod is fixedly connected to the top of the supporting column, a monitoring box is fixedly mounted at one end, away from the supporting column, of the mounting rod, and an air inlet is formed in the surface of the monitoring box. A connecting cavity, a detection cavity and a detection channel are formed in the monitoring box, and a humidity sensor is fixedly installed in the detection cavity. The humidity detection device has the beneficial effects that the sensitivity of the humidity sensor can be rapidly detected, the operation of disassembling the humidity sensor is avoided, and the working efficiency is improved; the height of the monitoring box can be adjusted, so that the humidity at different heights can be convenient
