Dilatometry testing is one of the in-situ geotechnical and rock mechanics tests that was introduced 54 years ago in Europe and then in the United States. Since its invention, this device has undergone changes and has been better equipped according to various needs in projects. Adding a geophone to calculate the soil shear wave velocity was one of these cases. In this project, an attempt was made to use an electronic vibration-sensitive sensor with a long life, lower cost, and smaller dimensions instead of a geophone as an electrical component. Investigating the possibility of receiving the soil shear wave velocity (Vs) and also achieving the maximum soil shear modulus (G) were other goals of this project. The blade and rod were designed using AutoCAD 3D software and turned with a CNC machine. The driver board was designed using Fritzing software and the PCB was manufactured manually, and then the electronic components were assembled. After completing the design and construction of the dilatometer, the in-situ test was performed at the under-construction Bahar Shiraz station on Line 6 of the Tehran Metro. The results of the constructed device showed that it is possible to measure soil parameters. The soil shear wave velocity Vs=504.5 m/s and the maximum shear modulus G0=4.33 MPa were measured. Also, in order to better evaluate the results of the device, it is recommended to perform a comparative test.
