It’s small, easy to use, and combines everything you need: a transmitter, receiver, and control circuit in one module. It works like a sonar, sending out sound waves to measure the distance to objects, just like how bats and dolphins sense their surroundings. This makes it an ideal ultrasonic sensor module for robotics and IoT applications where accuracy and reliability are essential.\u003c\/p\u003e\n\u003cp\u003eThis HC-SR04-Ultrasonic Range Finder can measure distances from 2 cm up to 400 cm with high accuracy, about 3 mm, making it the best distance measuring sensor 2cm to 400cm for both beginners and professionals. It’s reliable for many projects, from robotics to simple object detection, and works well even in different lighting conditions.\u003c\/p\u003e\n\u003cp\u003eThis HC SR04 ultrasonic distance sensor module has two main pins, Trigger and Echo, which connect easily to microcontrollers like Arduino, making it perfect as an ultrasonic distance sensor for Arduino projects where non-contact distance sensing is required. Understanding the HC-SR04 ultrasonic sensor working and pinout is simple, making it a go-to choice for students and developers.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv class=\"custom-metafields-guru-wrapper\"\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-Contact Distance Sensor:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eHC-SR04 Ultrasonic Range Finder measures 2–400cm and is suitable for various applications, making it the best distance measuring sensor 2cm to 400cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEndless Possibilities:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eUses sonar technology for accurate readings, ideal as an ultrasonic sensor module for robotics and IoT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact and Reliable:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eHC-SR04 features a small blind distance and provides stable performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Build:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eMade with high-quality materials, suitable for indoor and outdoor use\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUser-Friendly:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eEasy to install, perfect ultrasonic distance sensor for Arduino projects and beginners\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"custom-side-by-side-wrapper\"\u003e\n\u003cdiv class=\"bulk-order-wrapper\"\u003e\n\u003cdiv class=\"sidebar-custom-wrapper\"\u003e\n\u003cdiv class=\"bulk-order-container\"\u003e\n\u003cdiv class=\"product-section\"\u003e\n\u003cdiv class=\"bulk-enquiry-button\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"academy-banner-wrapper\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"ZEETRON","offers":[{"title":"Default Title","offer_id":48863197429977,"sku":"ZN117B","price":108.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/0706\/6073\/files\/1_HC_SR04_Ultrasonic_Sensor_1000x_665cf082-470b-4546-bc3b-3dbead060297.webp?v=1782653966"},{"product_id":"ldr-sensor-module","title":"LDR Sensor Module","description":"\u003cul\u003e\n\u003cli\u003eAdjustable sensitivity via blue digital potentiometer adjustment\u003c\/li\u003e\n\u003cli\u003eDigital output range: 0V to 5V\u003c\/li\u003e\n\u003cli\u003eAdjustable trigger level from preset\u003c\/li\u003e\n\u003cli\u003eLEDs indicating output and power (Power indicator in red and digital switch output indicator in green)\u003c\/li\u003e\n\u003cli\u003eUses LM393 comparator chip for stability\u003c\/li\u003e\n\u003cli\u003eEasy to install with an M3 mounting hole for attachment\u003c\/li\u003e\n\u003cli\u003eSuitable for detecting ambient brightness and light intensity\u003c\/li\u003e\n\u003cli\u003eDigital output for easy integration with microcontrollers\u003c\/li\u003e\n\u003cli\u003eComes with a power LED and status LED as indicators\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ZEETRON","offers":[{"title":"Default Title","offer_id":49009318232281,"sku":"ZN116A","price":65.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/0706\/6073\/files\/LDRSensorModuleLightDependentResistorModulePhotosensitive_Free1LED_harishprojects_1.webp?v=1785085029"},{"product_id":"sound-sensor-module","title":"Sound Sensor Module","description":"\u003cdiv class=\"custom-metafields-guru-wrapper\"\u003e\n\u003cul\u003e\n\u003cli\u003eUses LM393, Electret condenser microphone\u003c\/li\u003e\n\u003cli\u003eSignal output Indication\u003c\/li\u003e\n\u003cli\u003eSingle channel signal output\u003c\/li\u003e\n\u003cli\u003eThe output effective signal is low level.\u003c\/li\u003e\n\u003cli\u003eCan detect the intensity of the sound environment\u003c\/li\u003e\n\u003cli\u003eWith the retaining bolt hole, convenient installation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"ZEETRON","offers":[{"title":"Default Title","offer_id":49009323475161,"sku":null,"price":0.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/0706\/6073\/files\/microphone-sound-sensor-module_1000x_343d2ba3-14a7-48ce-8007-ae3051c6c7c3.webp?v=1785085361"},{"product_id":"5mm-ldr-light-dependent-resistor","title":"5mm LDR (Light Dependent Resistor)","description":"\u003cp\u003e\u003cspan\u003eA 5mm LDR photoresistor \u003c\/span\u003e\u003ca title=\"sensor\" href=\"https:\/\/robocraze.com\/collections\/sensors\" target=\"_blank\"\u003esensor\u003c\/a\u003e\u003cspan\u003e is made of a high resistance semiconductor.
