Waveshare Hall Element Switch Sensor Detector Hall Sensor Detection Module Magnetic for Detect Car AVR

I have purchased a few items from Waveshare and so far they have been a decent quality. What I like even more is that the Waveshare product page has a link to their wiki page, which provides instructions for use and links to examples. Many of these small hobby electronics come with no instructions and you are left searching for resources, but Waveshare does that work for you, at least enough to get you started. Packaged with the sensor you get a voltage comparator, sensitivity adjustment, and output feedback on the board. Comparing similar alternatives this is in the same price range for a single sensor. Overall this sensor is a good quality and has helpful resources to get started in whatever project you have lined up for it.

Fue un regalo y me comentan que funciona muy bien, no hay ninguna queja.
