Diagram for capacitive sensor with relay module

Diagram of connection of the capacitive sensor, for the autolevel function, with an relay module.

I drew this diagram, because an Internet friend, has this module, common in Arduino projects or as controller of a 220V silicone hotbed.

It is not the best solution, because it is noisy. But possibly, you have one, surplus, of an arduino project.

Is a remix from my own work, just in case, you have a relay module.

UPDATE 06/16/2018: Remember that you should not take literally the final positions, neither of the motherboard, nor of the endstop.

IT CAN BE DIFFERENT, on your motherboard and with YOUR endstop.
Both the connector and the endtop are only object references, not the position of the wiring.

REMENBER to change the input jumper to LOW or HIGH status, depending on the behavior required.
