Hi folks,
I have a inductive sensor that is connected in series with a pull up resistor. Now when I pass a metal object near the coil the Vcoil drop by a certain magnitude. My objective is to measure the magnitude of the voltage drop between the ORIGINAL Vcoil and the final voltage and hence amplify the reading and supply it to a peak detector Any suggestions??
