Optical water level sensor wiring

[Rob F]

I was so happy to find that sensor but it was a real disappointment. I haven't had time to get other sensors to try, currently I'm just selling the kit with 2 float switches, one for main and backup as I haven't had an issue with those yet but I do want something better. Some people use or looking to use IR sensor but currently those have to be Analog to work and a lot are digital or I2C. Any analog sensor will work but might need a resistor. Here's another style that should work ok but I haven't personally tried it.
