The materials we used: 1 elegoo uno R3, 3 f-m dupont wires and 1 water level detection sensor module.
the uno is connected to the water level sensor module with the help of f-m dupont wires. power supply is connected to 5V of uno, ground electrode is connected to GND, signal output is connected to the ports AO.we used the wet tissue for the moister, and tested the sensor with it.with the original code we tested the moister, and serial monitor shows the moister. And with the applied pressure the moister level was higher.
