A DIY FLUXGATE MAGNETOMETER BASED CURRENT PROBE

Introduction Current measurement can be really awkward when working with circuits. Voltage measurements are (usually) straightforward, but when it comes to current measurements the story is different. One typical approach is to insert a known resistance by breaking the circuit, and then measuring the voltage across it. This is difficult if one end of the resistor is not at ground potential, because oscillos ...

The Magnetometer using PIC16F688

I found several different magnetometer designs on Internet, but I tend to be very picky. None of those was what I needed - something that is sensitive enough to record the small magnetic field variations where I live (San Jose, California), robust enough to work for long periods of time without constant maintenance, and relatively easy to construct. Since the only place where I could permanently install the ...
