| Aug 30, 2021 at 16:18 | comment | added | Ilya | alright, I think I got what you mean. Maybe your idea will work. In any case, present full schematic. It could be something with power too. In fact, it most likely is. I would measure voltage on power rails of the sensor module. Also, it shouldn't matter much because the sensor uses very little current, but a wire of that length has noticeable non-zero resistance. And capacitance. You might want to put a resistor right on the output pin. Some 1k or 10k, because sensors don't like driving capacitive loads | |

| Aug 30, 2021 at 16:03 | comment | added | Ilya | so what exactly is its purpose? It can't measure anything useful for you; as for why it doesn't work, please, present full schematic. With module pins and power. | |
| Aug 30, 2021 at 15:48 | comment | added | Chukwuma Collins Ezenyinwa | I didn't immerse the sensor in water, I only connected a dry pvc hose to the sensor and used the pressure applied by the level rise of the water to increase air pressure in the hose. So there is no physical contact between the sensor and the water | |
