Whether you are repairing a high-end commercial coffee machine, designing a smart water dispenser, or building an automated irrigation system for a STEM project, the \u003cb data-path-to-node=\"6\" data-index-in-node=\"274\"\u003eYF-S401 Water Flow Sensor\u003c\/b\u003e provides the exact data you need. Built with a high-quality magnetic rotor and a Hall effect sensor, this device translates water movement into a readable electrical pulse, allowing your microcontroller to track fluid volume with exceptional accuracy.\u003c\/p\u003e\n\u003cp data-path-to-node=\"6\"\u003e \u003c\/p\u003e\n\u003ch3 data-path-to-node=\"7\"\u003e\u003cb data-path-to-node=\"7\" data-index-in-node=\"0\"\u003eHow the YF-S401 Solves Your Flow Control Problems\u003c\/b\u003e\u003c\/h3\u003e\n\u003cp data-path-to-node=\"7\"\u003eMechanical flow meters often suffer from wear and tear, leading to inaccurate readings and frequent replacements. The YF-S401 bypasses this issue entirely. By utilizing a \u003cb data-path-to-node=\"7\" data-index-in-node=\"221\"\u003eHall effect sensor\u003c\/b\u003e that is sealed completely away from the water pipe, it ensures that the internal electronics stay dry and safe. This translates to a longer lifespan and zero signal degradation over time.\u003c\/p\u003e\n\u003cp data-path-to-node=\"8\"\u003eFurthermore, integration is incredibly straightforward. With a standard three-wire output (Red for Power, Black for Ground, and Yellow for Signal), it connects seamlessly to popular microcontrollers like \u003cb data-path-to-node=\"8\" data-index-in-node=\"204\"\u003eArduino\u003c\/b\u003e and \u003cb data-path-to-node=\"8\" data-index-in-node=\"216\"\u003eRaspberry Pi\u003c\/b\u003e. You don't need complex adapters or proprietary boards to get started. Just hook it up, apply the basic frequency calculation formula, and you have a professional-grade flow measurement system ready to go.\u003c\/p\u003e","brand":"Sun Cheong Computer Company Limited","offers":[{"title":"Default Title","offer_id":43365322719383,"sku":"21PS001219","price":202.0,"currency_code":"TWD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0440\/4022\/4919\/files\/yf-s401-coffee-maker-flowmeter-top.jpg?v=1775796190","url":"https:\/\/scccltd.com\/en-tw\/products\/yf-s401-water-flow-sensor","provider":"Sun Cheong Computer Company Limited","version":"1.0","type":"link"}
