Banggood

I ordeted - "10Pcs DC 5V KY-003 Hall Magnetic Sensor Module For Arduino " but in pack I found only 9 Pcs (strange).

All Good just as expected

these work great with rare earth magnets which can be found on BG too. I found that on board led is very useful for visual feedback when using these as end stop switches. Recommend buying and price is unmatched anywhere on web.

Great component. Worked well with Wemos to make a garage roller door opening sensor system

Does what it says on the tin, be aware that they are polarized so they'll only detect magnets when they're a faced the right way,

Hi! I received the sensors well packaged. They work perfectly. Best regards, Escola
