It detects water and drops, and converts the amount to analog signals. Its sensitivity can be calibrated with the potentiometer. It works with all Friendly Elec boards, Raspberry Pi and Arduino boards.\u003cbr\u003e \u003cbr data-mce-fragment=\"1\"\u003eThe module has a series of exposed traces. The resistance of these exposed traces are proportional to the water level. This mechanism is used to measure the amount of water and therefore calculate the water level. It can be used to detect whether or not there is rainfall as well. \u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e","brand":"FriendlyELEC","offers":[{"title":"Default Title","offer_id":41087773278414,"sku":"LLS-01","price":1.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/4974\/6638\/products\/LLS-02-900x630.jpg?v=1649002946","url":"https:\/\/friendly-arm-tr.myshopify.com\/ko\/products\/water-drop-detection-sensor-module","provider":"Antallia","version":"1.0","type":"link"}
