Proton Precession Magnetometer

摘要

Instead of purchasing an expensive precession magnetometer, you can easily build a basic system for a fraction of the cost using a Keil MCB2130 board and an NXP LPC2138 microcontroller. James explains how. Uses for proton precession magnetometers (PPMs) include treasure hunting, archaeological research, and geophysical exploration. They are so popular that specific models are readily available for each field.
