Operating at 5V DC and consuming less than 2 mA, it includes three sensors, mounting brackets, and cables for quick integration into robotics, IoT, or automation projects. Its reliable 40kHz ultrasonic frequency and easy wiring make it a top choice for professionals seeking accuracy and efficiency. ## Description Characteristic: The HC-SR04 ultrasonic distance measuring module provides non-contact distance measuring function from 2cm to 450cm and high distance accuracy up to 3mm. Module consisting of ultrasonic transmitter, receiver and control circuit. Basic working principle: 1. Use IO mouth TRIG trigger distance, at least 10 high level US signals; 2. The module automatically sends eight 40KHz square waves and automatically detects whether a signal is returned. 3. I returned the signal, through the IO mouth, ECHO output a high level, the duration of the high level is the time of the ultrasonic wave from start to return. 4. Distance = test (high level time * speed of sound (340 m/s)) / 2; Operating voltage: DC 5V Operating current: less than 2mA Working frequency: 40Hz maximum range: 450CM Minimum range: 2 CM Measuring point: 15 degrees Input trigger signal: 10US TTL pulse Echo signal output: Output the TTL level signal, proportional to the range. Document link: https://www.adrive.com/public/rRKFHV/k000175.rar Note 1: The TRIP pin is an internal pull-up resistor of 10K. Use the IO port of the microcontroller to pull the TRIP pin low, and then give a pulse signal of more than 10us. The OUT pin is the switching output pin when this module is used as an anti-theft module. This pin is not used in the ranging module. Note 2: The module should be plugged into the circuit board first and then powered on to avoid high-level malfunction. If it occurs, it can be solved by repowering it. Delivery content: 3 X 4 Pin Ultrasonic Distance Measuring Sensor Module HC-SR04 3 X Mounting Bracket Female to Female Cable Male to Female Cable Review: Good Sensor - Really nice set with pretty much everything you need for a project. Used for a lap timer I made using a RaspberryPi and a few other things. Great for the price and the amount you get. As of now its works as intended and solid. Was less then a minute to have it up and running super easy to use. Very accurate per the code variables to tweak its sensitivity etc. Good deal, also fyi may need a voltage divider per your project. Review: Killer sensor deal - Awesome little Sensors. They worked perfect and came with plenty of hardware for different applications. I made a 3D file for printing a cover with a back plate to keep it dry and safe ## Features - Power supply: 5 V DC; static current: < 2 mA; Effective angle: < 15 Β°; Level output: bottom 0V; Recognition distance: 2 cm ~ 450 cm; Resolution: 0.3 cm. - Test removal: high timeline of the sound (340 m /s) /2 - On-board wiring methods: VCC, trig (control terminal), echo (receiving terminal), out (empty pin), GND. - Equipped with an anti-reverse pin socket, which makes the cabling much closer and more convenient. - Complete set, with 3PCS HC-SR04 Ultrasonic sensor module and 3 sets of Mounting Bracket and Cable. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D1MDP9V3 | | Best Sellers Rank | #87,884 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #12 in Ultrasonic Proximity Sensors | | Date First Available | April 13, 2024 | | Item Weight | 2.18 ounces | | Manufacturer | Ferwooh | | Package Dimensions | 6.81 x 3.11 x 0.75 inches | ## Images ![3PCS HC-SR04 Ultrasonic Sensor Module Distance Measuring Sensor Module Ultrasonic Ranging Module + 3 Sets Mounting Bracket with Cable - Image 1](https://m.media-amazon.com/images/I/61CXJgLZwUL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good Sensor *by D***M on September 12, 2025* Really nice set with pretty much everything you need for a project.
