Diagram for capacitive sensor with relay module

thingiverse

Diagram of connection between capacitive sensor and relay module for autolevel function. I created this diagram because a fellow online contributor has this module, which is commonly used in Arduino projects or as a controller for 220V silicone hotbeds. It's not the most ideal solution due to its noisy performance. However, if you have one lying around from an Arduino project, it could be worth using. This diagram is a remix of my original work, and I've included it here just in case you happen to have a relay module on hand. UPDATE 06/16/2018: Keep in mind that the final positions shown for the motherboard and endstop are not meant to be taken literally. They may vary depending on your specific setup. The connector and endstop mentioned in the diagram serve as reference points only, not actual wiring positions. Remember to adjust the input jumper to LOW or HIGH status according to your desired behavior. For a more reliable solution, I recommend checking out this alternative design: https://www.thingiverse.com/thing:2906283
