The telephone was invented by Alexander Graham Bell, who was awarded the first US patent for the device in 1876. The metal detector was developed by Alexander Graham Bell as well, specifically for the purpose of locating a bullet lodged in the body of President James Garfield after he was shot in 1881. Both inventions showcase Bell's contributions to communication and technology.

What are the difference between sensor and metal detector?
A sensor is a general device that detects changes in the environment, such as temperature, light, motion, or pressure, and converts them into signals. A metal detector, on the other hand, is a specific type of sensor designed only to detect the presence of metal using electromagnetic fields. In short, all metal detectors are sensors, but not all sensors are metal detectors.

How do you get metal through metal detectors?
In general, you can't get metal through metal detectors. Only the smallest bits of metal will not cause a metal detector to alarm. If the sensitivity of the detector is set too high, it may be possible to get a small piece of metal past the detector, but that is something that cannot be counted on.
