Abstract

Aimed at the request of the water content of the construction wall in different depth

the method of optimizing the structure and the size of capacitive sensor is strdied.A series of detectors with different detecting depth are developed by simulation and experiment.The construction wall is divided into some layers along the direction of depth

and the relationship between water content and the output of different sensors is fitted by means of experimental data.Through combination measurement

the water content in each layer can be obtained.Experimental results show that the distribution of the water can be calculated from the equations

and the test accuracy is decided by the amount of sensors.
