This is PIC16F73 base digital data capture unit with optional EMF reader. This data capture utility is design to work with most of the analog sensor inputs and by default it is equipped with EMF reader module. This unit use PIC16F73’s internal 8bit ADC to capture the analog signals.
EMF reader unit in this schematic is useful to detect variations of EM field in environment and it is mainly build around uA741 operational amplifier and 12mH detector coil. Normally EMF meters are used to trace electric wires, find hidden transmitters, and diagnose electric wiring problems (and to find ghosts too ☻).
