I have used a “Corrosion Resistant Capacitive Soil Moisture Sensor” lst year for my flower watering system. I have put them inside for the winter since I didn’t need them in winter. Now I wanted to build the system up again, but the sensor is not working anymore. Although the sensor itself seem to be corrosion resistant, the electronic is not. If stopped working maybe due to corrosion? Sensor Corroded
I tried to solder the joints to fix it, but It did not work. So rest i peace Capacitive Soil Moisture Sensor.
But how could I make it more resistant to corrosion? I try acrylic paint: Sensor Protected
