Can anyone tell me what I have to change in the schematic on this page: https://www.aaroncake.net/circuits/lightdrk.htm to be able to use it with 12V instead of 9V? Thanks.

Actually, what I'm looking for is something that will detect an object passing in front of it. But digging even farther, what I REALLY need is something that will detect water in a vertical pipe. I was thinking about using this and having something floating in the pipe to pass in front of the sensor at the top of the pipe, which will be dry. But anything will do as long as it activates a relay when it senses water. Float valves are too much money. And conductive sensors will rust too fast. Any suggestions guys? Thanks.
