It has very handy and compact construction. It offers excellent range accuracy and stable readings in an easy-to-use package. Its operation is not affected by sunlight or black material like Sharp rangefinders are (although acoustically soft materials like cloth can be difficult to detect).\u003c\/p\u003e\n\u003cp\u003eThe \u003cem\u003eTrigger\u003c\/em\u003e and the \u003cem\u003eEcho\u003c\/em\u003e pins are the I\/O pins of this module and hence they can be connected to the I\/O pins of the microcontroller\/Arduino. When the receiver detects the return wave the \u003cem\u003eEcho\u003c\/em\u003e pin goes high for a particular amount of time which will be equal to the time taken for the wave to return back to the sensor.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUltrasonic Ranging Module\u003cspan\u003e \u003c\/span\u003eHC-SR04\u003cspan\u003e \u003c\/span\u003eprovides 2cm-400cm non-contact distance sensing capabilities, Ranging accuracy up to 3mm.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #ff2a00;\"\u003e\u003cstrong\u003eWiring\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #ff2a00;\"\u003e\u003cstrong\u003e+5V\u003c\/strong\u003e(\u003cem\u003epositive\u003c\/em\u003e)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #ff2a00;\"\u003e\u003cstrong\u003eTrig\u003c\/strong\u003e(\u003cem\u003econtrol\u003c\/em\u003e)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #ff2a00;\"\u003e\u003cstrong\u003eEcho\u003c\/strong\u003e(\u003cem\u003ereceive\u003c\/em\u003e)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #ff2a00;\"\u003e\u003cstrong\u003eGND\u003c\/strong\u003e(\u003cem\u003enegative\u003c\/em\u003e)\u003c\/span\u003e\u003c\/p\u003e\n\u003cbr\u003e\u003chr\u003e\n\u003ch4\u003e\u003cstrong\u003eFeatures :\u003c\/strong\u003e\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eMeasures the distance within a wide range of 2cm to 400cm\u003c\/li\u003e\n\u003cli\u003eStable performance\u003c\/li\u003e\n\u003cli\u003eAccurate distance measurement\u003c\/li\u003e\n\u003cli\u003eHigh-density\u003c\/li\u003e\n\u003cli\u003eSmall blind distance\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Indian Hobby Center","offers":[{"title":"Default Title","offer_id":40156190048299,"sku":"2137","price":79.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/6796\/1387\/files\/HCSR04-Ultrasonic-Sensor-Module-for-Arduino-Raspberry-PI-1000x1000.jpg?v=1692795374","url":"https:\/\/www.indianhobbycenter.com\/products\/hc-sr04-ultrasonic-sensor","provider":"Indian Hobby Center","version":"1.0","type":"link"}
