HC-SR04 Ranging Detector Ultrasonic Distance Sensor with Cable by Corpco

Description

Product Overview

The HC‑SR04 ultrasonic ranging detector from Corpco is a compact, high‑performance sensor designed for precise distance measurement in a wide range of applications. Measuring just 1.3 × 1.3 × 0.05 inches and weighing only 0.35 ounces, the module offers a lightweight solution without sacrificing durability. It features an 8‑inch cable terminated with male and female connectors, allowing easy installation in tight spaces or on prototype boards. The sensor provides four clearly labeled pins – VCC, Trig, Echo, and GND – that simplify wiring to microcontroller platforms such as Arduino, Raspberry Pi, and other compatible development boards. Operating voltage is 5 V, and the device can reliably detect objects from 2 cm up to 400 cm, delivering accurate distance data with a resolution of 3 mm. The robust construction, combined with a low price point of $5.25, makes the HC‑SR04 an attractive choice for both hobbyists and professional engineers seeking cost‑effective sensing solutions.

Usage

Designed for versatility, the HC‑SR04 excels in a variety of environments. In robotics, it enables obstacle avoidance, wall‑following, and autonomous navigation by providing real‑time distance feedback. For industrial applications, the sensor can be integrated into level‑monitoring systems, conveyor belt controls, and safety interlocks where reliable proximity detection is essential. DIY enthusiasts often employ the module in smart home projects, such as automatic lighting, parking assistance, and water‑level alarms. Its compatibility with Arduino and Raspberry Pi means that developers can quickly prototype using popular libraries and example code, reducing development time and accelerating product iteration. The 8‑inch cable offers flexibility for mounting the sensor away from the main board, allowing designers to position the transducer in optimal locations while keeping the electronics protected.

FAQ

What is the maximum detection range of the HC‑SR04?

The sensor can reliably detect objects up to 400 centimeters (approximately 13 feet) away, with a minimum range of about 2 centimeters.

Can the HC‑SR04 be used with a Raspberry Pi?

Yes, the module is fully compatible with Raspberry Pi. You can connect the VCC, GND, Trig, and Echo pins to the Pi’s GPIO pins and use available Python libraries to read distance data.

Is the 8‑inch cable included with the sensor?

Yes, the package includes an 8‑inch cable terminated with male and female connectors, allowing flexible placement of the sensor relative to your main board.

What power supply voltage does the HC‑SR04 require?

The sensor operates on a 5‑volt DC supply, which is standard for most Arduino and Raspberry Pi boards.

How do I calibrate the sensor for accurate measurements?

Calibration is typically performed in software by adjusting the timing constants in your code. Most libraries provide default values that work well for most environments; however, you can fine‑tune them based on your specific setup and ambient conditions.
