Non Contact Voltage Tester DIY - How to Make Wireless AC Voltage Detector on PCB

This weekend learn about Non Contact Voltage Tester DIY - How to Make Wireless AC Voltage Detector on PCB by using a simple schematic, mainly based on CD4017BE IC which makes the tester more accurate and sensitive to detect voltage even behind the wall or inside the highly insulated wire or pipe. If you are an electrician or working on any electric project then this DIY tool will be very useful for you!
For Making this tool more attractive easy to make and professional, Well PCB sponsored their PCBs for this project.

This circuit used for concealed wiring , to identify break contact in this circuit

[@IdeasTv]

yeah somehow :)

[@tanvirmahmud1048]

Can there are any way to adjusting sensitivity?

[@IdeasTv]

not possible in this circuit, but you can do it with my another in which I'm using transistors instead of IC. checkout my channel for the video

[@tanvirmahmud1048]

@@IdeasTv if I use a potentiometer???
Is it possible with this circuit?

[@mihirsorathia8402]

Hello bro can u give me ur circuit dimensions , layer I want to order same circuit for this tester

Sir is there a diy tool that can detect ac 230 volts line inside 12 inch Walla.

[@IdeasTv]

12 inch is too much
