مستشعر تدفق ماء 0-30 ل/دقيقة DC 5-18 فولت YF-S201 بتقنية هول

Worked perfectly with my Arduino project to measure water flow from a small pump. The 1/2-inch threads made it easy to connect to standard plumbing fittings.

Had my Arduino project up and running in minutes thanks to the clear signal output from the Hall effect sensor—the 5-18V range makes it flexible for different setups. Flows are easy to read.

The brass threads on both ends are a nice touch for a part this cheap, and it screwed right onto my 1/2-inch pipe without any leaks. I've got it running at 12V with an Arduino and the pulse count is matching my manual bucket test within a few percent, which is plenty for my hydroponics rig.
