This metal detector circuit diagram is based on the TDA0161 monolithic integrated circuit , designed for metallic body detection by detecting the variations in high frequency Eddy current losses.
This metal detector schematic circuit is based on a transistor radio as an detector .This metal detector is total different that other metal detectors, because this circuit doesn't have a speaker .
This electronic liquid detector circuit diagram is based on the ULN2429 monolithic bipolar integrated circuit designed for detecting the absence or presence of many different types of liquids . The ULN2429 electronic liquid detector circuit can be used in automotive , home or industrial applications .
