Adopt IO trigger through supplying at least 10us of high level signal.  \u003cbr\u003e2. The module automatically send eight 40khz square wave and automatically detect whether receive?the returning pulse signal.  \u003cbr\u003e3. If there is signals returning, through outputting high level and the time of high level continuing is?the time of that from the ultrasonic transmitting to receiving. Test distance =(high level time * sound (340M\/S) \/ 2.  \u003cbr\u003e  \u003cbr\u003eNote:  \u003cbr\u003e  \u003cbr\u003eThis module is not suitable to connect with electric power, if you need to connect this module with?electronic power,then let the GND terminal of this module to be connected first,otherwise, it will affect the?normal work of the module  \u003cbr\u003e  \u003cbr\u003ePackage Included:  \u003cbr\u003e    \u003cbr\u003e50 x HC-SR04 Ultrasonic Module Distance Measuring Transducer  \u003cbr\u003e     \u003cp\u003e\u003cimg src=\"https:\/\/imgaz.staticbg.com\/images\/oaupload\/banggood\/images\/40\/A0\/526715a0-5c81-458e-91f9-03351b8fa1e7.jpg\"\u003e\u003c\/p\u003e   \u003cp\u003e\u003cimg src=\"https:\/\/imgaz.staticbg.com\/images\/oaupload\/banggood\/images\/CA\/8C\/4d9c2d38-e2ee-4ba2-a4b6-e2c6c36d143b.jpg\"\u003e\u003c\/p\u003e   \u003cp\u003e\u003cimg src=\"https:\/\/imgaz.staticbg.com\/images\/oaupload\/banggood\/images\/10\/81\/0c9f262b-a7d5-4b45-b03d-6c4068982e08.jpg\"\u003e\u003c\/p\u003e   \u003cp\u003e\u003cimg src=\"https:\/\/imgaz.staticbg.com\/images\/oaupload\/banggood\/images\/0F\/96\/178d4d0c-4cfd-45b8-8d9c-05faefd99fc8.jpg\"\u003e\u003c\/p\u003e   \u003cp\u003e\u003cimg src=\"https:\/\/imgaz.staticbg.com\/images\/oaupload\/banggood\/images\/40\/68\/3bbe8842-045f-4b85-a2b3-2977730f052e.jpg\"\u003e\u003c\/p\u003e   \u003cp\u003e\u003cimg src=\"https:\/\/imgaz.staticbg.com\/images\/oaupload\/banggood\/images\/C8\/FC\/98cc444f-1b88-49cd-a583-bc47aea0d1cb.jpg\"\u003e\u003c\/p\u003e   \u003cp\u003e\u003cimg src=\"https:\/\/imgaz.staticbg.com\/images\/oaupload\/banggood\/images\/D0\/BF\/e24eb877-6ff1-42fe-80d0-416fbaa6573a.jpg\"\u003e\u003c\/p\u003e   \u003cp\u003e\u003cimg src=\"https:\/\/imgaz.staticbg.com\/images\/oaupload\/banggood\/images\/3A\/1A\/e112ee66-672b-4e95-a069-d0069567177d.jpg\"\u003e\u003c\/p\u003e   \u003cbr\u003e","brand":"ZHIQIAN","offers":[{"title":"Default Title","offer_id":43935873204419,"sku":"ZHIQIAN-014413","price":1179.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0661\/4355\/1683\/files\/98cc444f-1b88-49cd-a583-bc47aea0d1cb.jpg?v=1725950348","url":"https:\/\/wrsss.com\/products\/50pcs-geekcreit-ultrasonic-module-hc-sr04-distance-measuring-ranging-transducers-sensor-dc-5v-2-45","provider":"Wrsss","version":"1.0","type":"link"}
