Operating at a low 5V and under 2mA current, it offers energy-efficient performance with a narrow <15° sensing angle for targeted detection. Compatible with popular Arduino boards, this compact, lightweight sensor is ideal for robotics, automation, and DIY projects requiring reliable proximity sensing. ## Features - HC-SR04 Ultrasonic Sensor：This is a device that can use sound waves to measure the distance of an object. It measures distance by emitting a sound wave of a specific frequency and listening to the bounce of that sound wave. The distance between the sonar sensor and the object can be calculated by recording the time elapsed between the generation of the sound wave and the bounce of the sound wave - Working Voltage: 5V DC；Quiescent current: less than 2mA - Ranging Distance：2cm - 450 cm；High precision: 0.3 cm - Effectual Angle: <15° - Test mode ：Test distance = ((Duration of high level)*(Sonic :340m/s))/2 ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B0B1MJJLJP | | Best Sellers Rank | #14,965 in Industrial & Scientific (See Top 100 in Industrial & Scientific) #1 in Ultrasonic Proximity Sensors | | Date First Available | March 4, 2022 | | Item Model Number | HC-SR04 | | Item Weight | 1.06 ounces | | Manufacturer | WWZMDiB | | Package Dimensions | 3.62 x 3.62 x 0.67 inches | ## Images ![2Pcs HC-SR04 Ultrasonic Sensor Module for Arduino (with Mounting Bracket) - Image 1](https://m.media-amazon.com/images/I/81Niip+c0aL.jpg) ![2Pcs HC-SR04 Ultrasonic Sensor Module for Arduino (with Mounting Bracket) - Image 2](https://m.media-amazon.com/images/I/71F-5pYk3xL.jpg) ![2Pcs HC-SR04 Ultrasonic Sensor Module for Arduino (with Mounting Bracket) - Image 3](https://m.media-amazon.com/images/I/71wdJb54flL.jpg) ![2Pcs HC-SR04 Ultrasonic Sensor Module for Arduino (with Mounting Bracket) - Image 4](https://m.media-amazon.com/images/I/71tUz8U87OL.jpg) ![2Pcs HC-SR04 Ultrasonic Sensor Module for Arduino (with Mounting Bracket) - Image 5](https://m.media-amazon.com/images/I/715osuOdERL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works Great *by on Reviewed in the United States July 29, 2026* Worked well for a water monitoring system, but will be buying the waterproof version. ### ⭐⭐⭐⭐⭐ Need to make sure you provide the cor *by on Reviewed in the United States June 30, 2026* Great product! ### ⭐⭐⭐⭐⭐ Measuring distance. *by on Reviewed in the United States March 17, 2026* These ultrasonic sensors are amazing. I am using mine connected to an Arduino Uno to measure distance to water in a bucket. As the water is pumped out the water level lowers to a point set in the Arduino code to activate a LED and display Refill Water Bucket on the LCD display, as well as play a tone.
