It is usually used at the inlet end to detect the amount of flow.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eWhen liquid flows through the sensor, a magnetic rotor will rotate and the rate of rotation will vary with the rate of flow. The hall effect sensor will then output a pulse width signal. Connect it to a microcontroller and you can monitor multiple devices such as your coffee maker, sprinkler or anything else, and control the water flow rate to suit your needs! \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe \u003c\/span\u003eGravity interface make it be compatible with Arduino IO Expansion Shield.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E38028-content1.webp?v=1791346754\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eNote:\u003cbr\u003e*A 20 mm rifled pipe is recommended\u003cbr\u003e*Avoid unit contact with corrosive chemicals\u003cbr\u003e*The unit must be installed vertically, tilted no more than 5 degrees\u003cbr\u003e*Liquid temperature should be less than 120 C to avoid damage to unit\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eInner Diameter: 11 mm\u003c\/li\u003e\n\u003cli\u003eOutside diameter: 20 mm\u003c\/li\u003e\n\u003cli\u003eProof Water Pressure: \u0026lt;1.75 MPa\u003c\/li\u003e\n\u003cli\u003eWater Flow Range: 1-30 L\/min\u003c\/li\u003e\n\u003cli\u003eVoltage Range: 3.5~12 V\u003c\/li\u003e\n\u003cli\u003eOperating Current: 15 mA (DC 5V)\u003c\/li\u003e\n\u003cli\u003eInsulation Resistance: \u0026gt;100 MΩ\u003c\/li\u003e\n\u003cli\u003eAccuracy: ±5% (2~30L\/min)\u003c\/li\u003e\n\u003cli\u003eThe Output Pulse High Level: \u0026gt;4.7 VDC (DC input voltage 5 V)\u003c\/li\u003e\n\u003cli\u003eThe Output Pulse Low Level: \u0026lt;0.5 VDC (DC input voltage 5 V)\u003c\/li\u003e\n\u003cli\u003eOutput Pulse Duty Ratio: 50% ± 10%\u003c\/li\u003e\n\u003cli\u003eWater-flow Formula: 1L = 450 square waves\u003c\/li\u003e\n\u003cli\u003eWorking Humidity Range: 25% ~ 95% RH (no frost)\u003c\/li\u003e\n\u003cli\u003eDimension: 62*36*35 mm\/2.44*1.37*1.37 inches\u003c\/li\u003e\n\u003cli\u003eWeight: 52g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eShipping List\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGravity - Water Flow Sensor - 1\/2\" x1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDocuments\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/wiki.dfrobot.com\/sen0217\/\" target=\"_blank\"\u003eProduct Wiki\u003c\/a\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DFRobot","offers":[{"title":"Default Title","offer_id":67582139760717,"sku":"E38028-001","price":23.87,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E38028-win1.jpg?v=1791346788","url":"https:\/\/www.mlab.com.au\/products\/gravity-water-flow-sensor-1-2-for-arduino","provider":"MLAB","version":"1.0","type":"link"}
