Affiliate Disclosure
Last updated: August 4, 2026
FTC Disclosure: comparator.online is a free resource. Some links on this site are affiliate links. We may earn a commission when you click these links and make a purchase, at no additional cost to you.
What This Means
When you see a "Buy" or "Purchase" link on our site that goes to AliExpress, Amazon, LCSC, or other retailers, we may receive a small commission. The price you pay is the same whether you use our link or go directly to the retailer.
Our Affiliate Partners
- AliExpress Affiliate Program - for LM393 sensor modules
- Amazon Associates - for components and tools
- LCSC Affiliate Program - for electronic components
Editorial Independence
Our recommendations are based on technical merit, not commission rates. We recommend parts that are genuinely suitable for the use case. Affiliate partnerships never influence our calculator logic or tutorial content.
Why Affiliate Links?
They help us keep comparator.online free. Commissions from your purchases fund development of new calculators and tutorials.
