Abstract：Aiming at the real-time monitoring requirements of harmful gases in theconstruction project environment，aconstruction project environment acquisition system based on wireless network is proposed.This paper focuses on the preparation of sensors for the detection of key pollutants such as CO，NO2 and VOCs，that is，ZnO /rGO composites with hierarchical pore structure were prepared byKGM biological template method to improve the performance of the sensor.Finaly，the gassensitivitytest shows thatthe CO gas sensor prepared inthis paper has the best performance in the working temperature range of ，and the sensing sensitivity to CO is 53.2±0.5 nAppm. The NO2 gas sensor can work at room temperature，and the sensitivity to NO 12 gasis 1.4±0.3 nAppm; the VOCs gas sensor has the best performance in the operating temperature range of 260±5∘C ，and the sensitivity to VOCs gas is as high as 379.4±0.5 nAppm. The system test results show that the construction project environment acquisition system based on wireless network can maintain good communication performance within 100m ，and the packet acceptance rate exceeds 98% ，which ensures the timeliness and reliability of data transmission.It provides reliable technical support for environmental collection of construction projects.
