{"product_id":"contactless-water-level-sensor-module","title":"Contactless water level sensor module","description":"\u003cp\u003eThis practical module can sense the presence of water. It is contactless because there is no sensing element that makes physical contact with the water. The sensor is even able to detect the presence of water through small thicknesses of plastic, glass, ceramic, and other non-metallic materials.\u003c\/p\u003e\n\u003cp\u003eThe sensor features a built-in red indicator LED that lights up when water is detected and the detection signal will output a high signal when water is present. The polarity of the detection signal can be changed by grounding the black wire, which will change the detection signal type to an active low signal. The sensor's sensitivity can be adjusted by opening the top cover and turning the blue potentiometer.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003edetects the presence of water using a contactless method\u003c\/li\u003e\n\u003cli\u003esensor is able to penetrate through small thicknesses of plastic, glass, ceramic, and other non-metallic materials\u003c\/li\u003e\n\u003cli\u003eadjustable sensitivity\u003c\/li\u003e\n\u003cli\u003econfigurable output polarity (active high or active low)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003esupply voltage: 5 - 24 V DC\u003c\/li\u003e\n\u003cli\u003eoperating current: 5 mA max.\u003c\/li\u003e\n\u003cli\u003econnector: 4 pin dupont\u003c\/li\u003e\n\u003cli\u003ecable length: ± 50 cm\u003c\/li\u003e\n\u003cli\u003edimensions (W x L x H): 28,3 x 28,3 x 16,8 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDocumentation\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.velleman.eu\/downloads\/25\/prototyping\/manual_wpse472.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eManual\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.velleman.eu\/downloads\/doc\/ce_wpi471_wpi474_wpm300_wpm456_wpm457_wpm458_wpm461_wpm466_wpm603_wpse472_wpse473_wpse475_wpse477_wpsh455.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eCE Document\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Velleman","offers":[{"title":"Default Title","offer_id":40162797322323,"sku":"WPSE472","price":12.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/wpse472.jpg?v=1659976635","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/contactless-water-level-sensor-module","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
