Review on Floor Water Sensor Flood Detection by Shane Minter

Just received this item. Use it to automatically add water to the pool. I have a 12-bit ADC connected to it. A 10 MΩ resistor divider is required. Several tests were performed, including being completely submerged in water for several hours and then being completely removed from the water. Works perfectly. As the device dries, the voltage approaches 0V. Will go into production shortly. Update: Unfortunately, after one season, pool water chemistry caused the wires to erode. As a result, my use may require a different sensor. At the same time, the sensor worked perfectly until erosion.
