Update ltr501.rst

[bennop]

Description:

in "proximity":
changed expression describing relation of counts to distance - never heard of "inversely exponential".

Should now be correct based on a physics-based intuition: radiation intensity drops with 1 over r^2 - so should the counts.

Checklist:

• I am merging into next because this is new documentation that has a matching pull-request in esphome as linked above.
  or
• I am merging into current because this is a fix, change and/or adjustment in the current documentation and is not for a new component or feature.

Walkthrough

The pull request modifies the ltr501.rst documentation to improve clarity and accuracy regarding the Lite-On Ambient Light and Proximity Sensors. Key updates include a refined description of supported sensor models (LTR-301ALS, LTR-501ALS, LTR-558ALS) and an adjustment in the explanation of the proximity sensor's functionality. The document's structure has been slightly altered for readability, while the configuration variables section has been formatted for consistency. The example configuration remains unchanged, ensuring practical guidance for users.

113-113: Approved: Improved accuracy in proximity sensor description

The change from "inversely exponential to the distance" to "inversely proportional to the distance squared" is a significant improvement in accuracy. This new description correctly reflects the inverse square law that governs the relationship between radiation intensity and distance. It provides a more precise understanding of how the proximity sensor's raw count value relates to the distance of an object, which is crucial for users implementing this sensor in their projects.

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
