The water flow meter sensor comes with three wires: red (5-24VDC power), black (ground) and yellow (Hall effect pulse output). To use this sensor you will need a controller such as an \u003ca href=\"https:\/\/www.makerlab-electronics.com\/product\/arduino-uno-r3\/\"\u003eArduino\u003c\/a\u003e to count the pulses, and an \u003ca href=\"https:\/\/www.makerlab-electronics.com\/product\/16x2-lcd-display-black-green\/\"\u003eLCD\u003c\/a\u003e to display the values.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit-Flow-Meter\"\u003eWe have an example Arduino sketch that can be used to quickly test the sensor\u003c\/a\u003e - it will calculate the approximate quantity of fluid in liters and display on an LCD or the serial monitor.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eElectrical Sepcification:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWorking Voltage: 5 to 18VDC\u003c\/li\u003e\n\u003cli\u003eMax current draw: 15mA @ 5V\u003c\/li\u003e\n\u003cli\u003eWorking Flow Rate: 1 to 30 Liters\/Minute\u003c\/li\u003e\n\u003cli\u003eWorking Temperature range: -25 to 80°C\u003c\/li\u003e\n\u003cli\u003eWorking Humidity Range: 35%-80% RH\u003c\/li\u003e\n\u003cli\u003eMaximum water pressure: 2.0 MPa\u003c\/li\u003e\n\u003cli\u003eOutput duty cycle: 50% +-10%\u003c\/li\u003e\n\u003cli\u003eOutput rise time: 0.04us\u003c\/li\u003e\n\u003cli\u003eOutput fall time: 0.18us\u003c\/li\u003e\n\u003cli\u003eFlow rate pulse characteristics: Frequency (Hz) = 7.5 * Flow rate (L\/min)\u003c\/li\u003e\n\u003cli\u003ePulses per Liter: 450\u003c\/li\u003e\n\u003cli\u003eDurability: minimum 300,000 cycles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMechanical Specification:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1\/2\" NPS nominal pipe connections, 0.78\" outer diameter, 1\/2\" of thread\u003c\/li\u003e\n\u003cli\u003eSize: 2.5\" x 1.4\" x 1.4\"\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Others","offers":[{"title":"Default Title","offer_id":42290957877439,"sku":"MLE00581","price":250.0,"currency_code":"PHP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0531\/3419\/6927\/files\/c6d51b0c150c17b72f537f21be75113d.jpg?v=1735816318","url":"https:\/\/makerlab.ph\/products\/water-flow-meter-plastic-1-2","provider":"Makerlab PH","version":"1.0","type":"link"}
