Hello I am hoping someone can help me find this sensor in some kind of water proof version. We use it for a dog sport where they swim and our time for it. the sensor has a hole on the top and a hole on the back where water is getting in and completing the circuit making it fail. if I could find one that is waterproof that does the same thing I will purchase 25 of them. Please help I will attach a picture of the holes I’m talking about.
In the picture I notice a website for the manufacturer. Have you tried contacting them? They might be able to help, either by providing ones that are already water resistant or by suggesting some way of making them water resistant.
