- @NickS. - That's a nice comment your wrote! The "Also, your equation is wrong..." part is brilliant, and would be part of a great answer. Perhaps you are not aware that answers in the comments on Arduino SE are frowned upon.VE7JRO– VE7JRO2023-07-12 00:45:43 +00:00Commented Jul 12, 2023 at 0:45
- @NickS. - Why not put your "I just gave pointers" part of your comment into an answer? I am certain that the long term members of this stack will agree that answers and partial answers are not welcome in the question's comment section :) NGVE7JRO– VE7JRO2023-07-12 02:28:18 +00:00Commented Jul 12, 2023 at 2:28
- GND of Arduino should be connected to the GND of the sensor power supply (even if the sensor uses 12V or 24V). Without this common ground, the analog voltage won’t be referenced properly, and you'll get unstable or incorrect readings. Please check.tepalia– tepalia2025-04-21 08:42:13 +00:00Commented Apr 21 at 8:42

How to Edit
- Correct minor typos or mistakes
- Clarify meaning without changing it
- Add related resources or links
- Always respect the author’s intent
- Don’t use edits to reply to the author
How to Format
- create code fences with backticks ` or tildes ~ ```
like so
``` - add language identifier to highlight code ```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- indent code by 4 spaces
- backtick escapes
`like _so_` - quote by placing > at start of line
- to make links (use https whenever possible) <https://example.com>[example](https://example.com)<a href="https://example.com">example</a>
How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. arduino-uno), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
