{"product_id":"ultrasonic-sensor-module-hcsr04","title":"ULTRASONIC SENSOR MODULE HCSR04","description":"\u003cp\u003eThe HC-SR04 Ultrasonic Distance Sensor measures distance via sonar — similar to how bats navigate. Trigger pin sends an 8-cycle ultrasonic burst; Echo pin goes HIGH for a duration proportional to round-trip travel time. Accurate to 3mm. Not affected by sunlight or black surfaces. Acoustically soft materials (cloth, foam) may reduce detection reliability.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eWiring:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eVCC — 5V\u003c\/li\u003e\n\u003cli\u003eTrig — Digital output (from MCU)\u003c\/li\u003e\n\u003cli\u003eEcho — Digital input (to MCU)\u003c\/li\u003e\n\u003cli\u003eGND — Ground\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eModel: HC-SR04\u003c\/li\u003e\n\u003cli\u003eOperating Voltage: 5V\u003c\/li\u003e\n\u003cli\u003eAverage Current: 2mA\u003c\/li\u003e\n\u003cli\u003eUltrasonic Frequency: 40kHz\u003c\/li\u003e\n\u003cli\u003eSensing Angle: 15°\u003c\/li\u003e\n\u003cli\u003eRange: 2–400cm\u003c\/li\u003e\n\u003cli\u003eAccuracy: ±3mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eApplications:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eObstacle detection and avoidance in robots\u003c\/li\u003e\n\u003cli\u003eParking sensor and proximity alert systems\u003c\/li\u003e\n\u003cli\u003eLevel and fill sensing in tanks\u003c\/li\u003e\n\u003cli\u003eArduino distance measurement projects\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Powered by INFINITY WORKS","offers":[{"title":"Default Title","offer_id":47371696341046,"sku":"TW374","price":76.16,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0772\/9335\/5062\/files\/ULTRASONIC_SENSOR_MODULE_HCSR04.jpg?v=1787646179","url":"https:\/\/tecwizdom.com\/products\/ultrasonic-sensor-module-hcsr04","provider":"Tecwizdom.com","version":"1.0","type":"link"}
