  1. Great video but could you please be a little more specific with your instructions, eg. How long does it have to dry, how long does it have to be in the saltwater etc.

  2. Such a great idea! I also like the way you presented the instruction. Can I connect this to a 5 volt buzzer to make it sound louder? theoretically, can you connect a buzzer the voltage that matches equally or less than the battery used? And would this cause any kind of short out to start a fire should the water rise high enough to cover the whole thing?

  3. I have a question. How to make the buzzer stop without change the sponge or put it off from the battery?

  4. Do you think that this could be used to power an ESP01 (ESP8266) WIFI microcontroller so that it sends a message to my home automation? The battery would have to be changed to a 3.3v source but do you think that the sponge would be able to source enough power through it to power the chip?

  5. I have a doubt. How to off that immediately after ringing .. & also can we dry it by fan instead of dryer since dryer is unavailable

  6. Sir… I have completed doing this.. But without any water it is ringing Sir.. Could you please help me to solve this as it is my mini project..

  7. Sir as I said I have12v buzzer.. Is it correct to connect buzzer 's red wire& battery clip's red wire.. R otherwise plz tell how to connect those wires(red& black)
