I am working on a sensor that detects 120V AC power over a line and if voltage is detected the electronics turn on a light. I didn't design the sensor or the switch so I can't control that part. What is happening when I hook the sensor up to the 4 way switch in my house is the sensor is sensing an 80V no amperage signal on the off leg. I suspect that it is voltage induced into the off line in the 12/3 line because one leg always has power. This keeps my sensor from shutting off the power to the light even when the switch is not sending power to the sensor.
How can I either remove (sink) the no amperage power off the line or block the no amperage power from getting to the sensor while allowing the high output 120v to come through when the power is on? I am hoping for a small low cost solution.
