Step 6Silicone Sealant to Waterproof
The copper cap was hammered into 1/2 inch PVC pipe to make the probe. Then, I used aquarium, silicone sealant to seal the gaps as I pushed the sensor into the probe.
The entire length of the probe was filled with sealant to complete the waterproofing. Note - However, you should probably fill it with a non-conductive grease. Then, clean the end of any grease and seal it with the silicone sealant. The sealant will never set if it is not exposed to air.
