Sir, Dont use any kind of background music, use your own voice to explain the circuit functioning along with circuit diagram..👎👎👎

[@mithila93]

I have made this. Workings perfectly. After few days it’s not working.
What's the problem?

[@user-sc4np4yt2n]

You can't dip into water permanently, it will initiate electrolysis process, wire will get corrosive

[@devanthiranvijay]

Is this works only on salt water i tried this but works on salt water only

[@anuragprojects]

Yes
