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\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eCheck out the best selection of \u003ca href=\"https:\/\/robocraze.com\/collections\/distance-proximity-sensors\"\u003e\u003cspan\u003e\u003cstrong\u003eDistance Sensors\u003c\/strong\u003e\u003c\/span\u003e\u003c\/a\u003e.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote: \u003c\/strong\u003e\u003cspan\u003eThe HC-SR04 sensor has a 5V output (which needs to be reduced to 3.3V to work with the Raspberry Pi).\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eRead our blog on \u003ca title=\"How to Connect Ultrasonic Sensor To Raspberry Pi\" href=\"https:\/\/robocraze.com\/blogs\/post\/interfacing-ultrasonic-sensor-with-raspberry-pi-4-gpio\" target=\"_blank\"\u003ehow to connect ultrasonic sensor to Raspberry Pi.\u003c\/a\u003e\u003c\/p\u003e\n\u003ch3\u003eLooking for the Best Price for the HC SR 04 Ultrasonic Sensor Online?\u003c\/h3\u003e\n\u003cp\u003eAt Robocraze, the HC-SR04 ultrasonic sensor price in India starts at ₹69, and may vary based on ongoing offers, stock availability, and bundled deals.
