It operates at a voltage of 5V DC with a static current of less than 2mA, offering a detection range of 2cm to 450cm and an impressive precision of up to 0.3cm. Encased in a waterproof powder-coated aluminum housing, this sensor is built to withstand various environments, making it an essential tool for any tech enthusiast. ## Description The UraXx HC-SR04 waterproof ultrasonic sensor uses sonar to measure distance to an object. It offers excellent range accuracy and stable readings in an easy-to-use package. It operation is not affected by sunlight or black material like Sharp rangefinders are (soft materials like cloth can be difficult to detect). Module main technical parameters: 1.Working Voltage : 5V(DC) 2.Static current: Less than 2mA. 3.Output signal: Electric frequency signal, high level 5V, low level 0V. 4.Sensor angle: Not more than 15 degrees. 5.Detection distance: 2cm-450cm. 6.High precision: Up to 0.3cm 7.Input trigger signal: 10us TTL impulse 8.Echo signal : output TTL PWL signal Mode of connection: 1.VCC 2.trig(T) 3.echo(R) 4.GND The basic operation principle is below : use IO port TRIG to trigger ranging. It needs 10 us high level signal at least Module will send eight 40kHz square wave automatically, and will test if there is any signal returned. If there is signal returned, output will be high level signal via IO port ECHO. The duration of the high level signal is the time from transmitter to receiving with the ultrasonic. Testing distance = duration of high level*sound velocity(340m/s) / 2 You can use the above calculation to find the distance between the obstacle and the ultrasonic module. This UraXx HC-SR04 Ultrasonic/Sonar Distance Measuring Sensor Module is Waterproof Powder Coated Aluminium Casing For Robotics and Automation Project. ## Features - Working Voltage : 5V(DC) - Static current: Less than 2mA - Output signal: Electric frequency signal, high level 5V, low level 0V - Sensor angle: Not more than 15 degrees - Detection distance: 2cm-450cm and High precision: Up to 0.3cm ## Technical Specifications | Specification | Value | |---------------|-------| | Batteries Required | No | | Batteries Included | No | | tech_spec_battery_description_toys | No batteries required | | Material Type(s) | Aluminium | | Colour | Black | | Package Dimensions | 8 x 8 x 8 cm; 80 g | | Item part number | US-120 | | Manufacturer | UraXx | | Item Weight | 80 g | ## Images ![UraXx HC-SR04 Ultrasonic/Sonar Distance Measuring Sensor Module in Waterproof Powder Coated Aluminium Casing for Robotics and Automation Project - Image 1](https://m.media-amazon.com/images/I/61KSnAp8NxL.jpg) ![UraXx HC-SR04 Ultrasonic/Sonar Distance Measuring Sensor Module in Waterproof Powder Coated Aluminium Casing for Robotics and Automation Project - Image 2](https://m.media-amazon.com/images/I/61QV4iH5oPL.jpg) ![UraXx HC-SR04 Ultrasonic/Sonar Distance Measuring Sensor Module in Waterproof Powder Coated Aluminium Casing for Robotics and Automation Project - Image 3](https://m.media-amazon.com/images/I/61qhmNRIVpL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very Accurate Readings *by S***I on 5 October 2019* Very Accurate Readings ### ⭐⭐⭐⭐ Good product *by A***R on 6 September 2018* Ultrasonic sensor is waterproof, Quality is good .
