{"product_id":"water-sensor","title":"WATER SENSOR","description":"\u003cp\u003eWater Presence Sensor with parallel exposed conducting traces. Grounded traces are interlaced with signal traces held high by a 1MΩ pull-up resistor. When water bridges a sensor trace to a ground trace, output voltage drops — detectable on Arduino digital or analog pins. Analog output 0–4.2V proportional to water contact area. Low power (\u0026lt;20mA).\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003ePin Definition:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eS — Signal (analog output)\u003c\/li\u003e\n\u003cli\u003e+ — 5V supply\u003c\/li\u003e\n\u003cli\u003e− — GND\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eWorking Voltage: 5V\u003c\/li\u003e\n\u003cli\u003eWorking Current: \u0026lt;20mA\u003c\/li\u003e\n\u003cli\u003eOutput: Analog (0–4.2V)\u003c\/li\u003e\n\u003cli\u003eDetection Area: 40 × 16mm\u003c\/li\u003e\n\u003cli\u003ePCB Dimensions: 65 × 20 × 8mm\u003c\/li\u003e\n\u003cli\u003eWorking Temperature: 10–30°C\u003c\/li\u003e\n\u003cli\u003eWeight: 3g\u003c\/li\u003e\n\u003cli\u003eCompatible: Arduino UNO, Mega 2560, ADK\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eApplications:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eRainfall detection\u003c\/li\u003e\n\u003cli\u003eLiquid leakage detection\u003c\/li\u003e\n\u003cli\u003eTank overflow alarm\u003c\/li\u003e\n\u003cli\u003eArduino water presence sensing projects\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Powered by INFINITY WORKS","offers":[{"title":"Default Title","offer_id":47371697291318,"sku":"TW394","price":20.4,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0772\/9335\/5062\/files\/WATER_SENSOR.png?v=1787646174","url":"https:\/\/tecwizdom.com\/products\/water-sensor","provider":"Tecwizdom.com","version":"1.0","type":"link"}
