Hi My name is Raash and I’m newbie for arduino. I want to make DIY Water detection using Arduino. I have check many forum regarding this topic. One of the related project that I found is How to Make an Arduino Water Detection Alarm at https://programmingelectronics.com/how-to-make-an-arduino-water-detection-alarm-project/. I have follow all the instruction as in the above forum and build the exact circuit as shown above in forum to make water detection using arduino but it doest not work for me. The circuit just can’t overcome the resistance of the water.
What might be the problem
- I think the 5v power source is not enough and though want to increase the power source to 9v or 12v using external power source like battery but I scare this will burn the arduino uno board
Below shows the image of circuit of water detection using arduino from the forum How to Make an Arduino Water Detection Alarm which extracted from https://programmingelectronics.com/how-to-make-an-arduino-water-detection-alarm-project/.
Can anybody help me how to solve the problem?
