I have not measured the output. It did not change with the LED. I connected it to the endstop positive and ground pins.Quote

... several questions: - have you measured the output? - did it change with the LED or not? - which driving voltage (6-36V!) and how did you connect it to the 5V input?

I am not testing with my heated bed, so I will cross that bridge once I get the probe to switch logic. I am testing with an aluminum build plate that works with my Printrbot probe. I already connected them like that. I have not tried using 12V though. I do not understand why I would need 12V if the Printrbot probe works on Printrboard and RAMPS with 5V, but I will try 12V as soon as I get a voltage regulator.Quote

Using sensor 1 that is the correct type, connect brown to + blue to - and black to signal. Do M119 if shows triggered switch logic, do M119 and verify that is open, put a metal close to it and do M119 again should say triggered, if not, then you will have to used 12 volts and a voltage divider or LM7805 for signal to ramps.
Now this might be an stupid question: what kind of heated bed you have? Do you have enough metal there for the sensor to work properly?. I used capacitive sensors instead because they read any material and they read the top and not bottom of bed (glass), yes you need to have a table of offsets for different bed temperatures, but easy to do and to me they are more accurate.

Will this work?Quote

Your solution sounds very interesting. Do you deal with temperature drift in firmware or hardware? I see you also experimenting with ultrasound sensor. I could not find a link to schematics on your website. Do you mind posting a link?
