robosang WROTE:What is the initial voltage? Water level but you use a drop of water? Not really understand your statement.
robosang WROTE:What is the initial voltage when there is no water? 5V or 0V? How you detect the sensor? I do not have the sensor, just curious to know the working condition. You use digital input or analog to detect the sensor?
What do you mean by erodible? A photo of the hardware setup would be helpful.
