| Aug 31, 2021 at 20:09 | comment | added | Chukwuma Collins Ezenyinwa | Thanks for your reply, I found out what the problem was. I removed the 10kOhm resistor that I initially used as a pull-down resistor, I found out it was conflicting with the internally built 5kOhm resistor, so the long wire had a huge voltage drop . It's working fine now. | |

Show a complete wiring diagram (the conductors you are using in the cable are important). What's the current consumption of the sensor? It's not listed in the spec sheet. What wire gauge are you using? | |

| Aug 30, 2021 at 17:23 | comment | added | Ilya | you can't. edit the post | |
| Aug 30, 2021 at 16:43 | comment | added | Chukwuma Collins Ezenyinwa | Pardon me, but I can't seem to figure out how to post pictures/schematics here in the comment section | |
| Aug 30, 2021 at 15:56 | comment | added | Chukwuma Collins Ezenyinwa | The sensor works with longer distance. I think I just didn't connect it properly. I connected pin 2 to Arduino RAW pin, while pin 1 goes to GND and pin 5 goes to Analog pin A0. Lastly, how do I post pictures here in the comment section (if it's possible)? | |

| Aug 30, 2021 at 11:58 | comment | added | Kartman | the sensor is not expected to be run via a 20m wire. You might want to reconsider your choice of sensor or your physical design. | |
