{"product_id":"capacitive-pipeline-liquid-level-sensor","title":"Capacitive Pipeline Liquid Level Sensor","description":"\u003cp\u003eThis capacitive pipeline liquid level sensor is suitable for non-metallic pipes with a diameter of 6mm. The sensor outputs digital high\/low level (low when liquid is detected) and adopts a 3-pin DuPont connector which can be used in beverage machines, small water pipe level detection and infusion pipe level detection scenarios.\u003c\/p\u003e\n\u003ch2\u003eWorking Principle\u003c\/h2\u003e\n\u003cp\u003eThe liquid level sensor uses the sensing capacitance of water to detect the presence of liquid.\u003c\/p\u003e\n\u003cp\u003eWhen there is no liquid approaching the sensor, the sensor has a certain static capacitance due to the distributed capacitance. When the liquid level slowly rises close to the inductor, the parasitic capacitance of the liquid will be coupled to the static capacitor, causing the final capacitance of the inductor to become larger.\u003c\/p\u003e\n\u003cp\u003eThe changed capacitance signal is then input to the control IC for signal conversion, which will change. The capacitance is converted into the amount of change of an electrical signal and then a certain algorithm detects and judges the degree of the change. When the amount of change exceeds a certain threshold, the liquid level is considered to reach the sensing point.\u003c\/p\u003e\n\u003ch2\u003eConnection Example (Arduino)\u003c\/h2\u003e\n\u003cp\u003e\u003cimg alt=\"SEN0509 Example (Arduino)\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0176\/3274\/files\/SEN0509-9_1.jpg?v=1644345732\u0026amp;width=700\"\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCapacitive pipeline sensor\u003c\/li\u003e\n\u003cli\u003eFor 6mm non-metallic pipes\u003c\/li\u003e\n\u003cli\u003e3-pin DuPont connector\u003c\/li\u003e\n\u003cli\u003eHigh sensitivity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eWorking Voltage: 2.5~5.5VDC\u003c\/li\u003e\n\u003cli\u003eWorking Current: 5V, 290uA \/ 3V, 235uA\u003c\/li\u003e\n\u003cli\u003eOutput: LOW (liquid detected), HIGH (no liquid detected)\u003c\/li\u003e\n\u003cli\u003eHysteresis: ±0.25%FS\u003c\/li\u003e\n\u003cli\u003eInterval Medium: plastic\u003c\/li\u003e\n\u003cli\u003eProtection Level: IP62\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: -20~100℃\u003c\/li\u003e\n\u003cli\u003eWeight: 3g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eProduct Wiki and sample code\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePackage Contents\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x Capacitive Pipeline Liquid Level Sensor\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DFRobot","offers":[{"title":"Default Title","offer_id":48624297214170,"sku":"sts1789689099604","price":8.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0824\/8318\/3834\/files\/capacitive-pipeline-liquid-level-sensor_1.jpg?v=1789689104","url":"https:\/\/memoryfoamwear.shop\/products\/capacitive-pipeline-liquid-level-sensor","provider":"My Store","version":"1.0","type":"link"}
