Preliminary studies on the application of smart phone magnetic Hall sensors for corrosion monitoring of burried steel rebars

Nowadays, smartphones have become an integral part of human life. It is mainly used for communication purposes and entertainment applications. Educational programs are almost universally ignored by the public. One of the useful applications of smartphones in the corrosion industry is the use of Hall effect sensor. The Hall effect sensor is located on the left half of smartphones. These sensors are used to detect the magnetic property of the metal and the location of metals on the bottom surface of a barrier or protector and to detect intentional corrosion of metals on the bottom surface. These tests are a type of simulation, in other words, hiding metals under an obstacle such as cardboard and detecting its metallic properties and detecting the extent of metal corrosion by the Hall effect sensor of a smartphone, a type of test simulation to perform these types of tests in structures concrete is in the real world. Therefore, for convenience, instead of using ۳D scanning devices to evaluate and monitor corrosion, these types of tests can be performed by analyzing the output signals of the mobile phone Hall effect sensor.
