It delivers high accuracy up to 0.3cm by emitting 40kHz ultrasonic pulses and measuring echo return time, making it ideal for professional-grade DIY projects and industrial applications. ## Description Specifications: This performance of the sonic sensor distance measuring module is stable, measure the distance accurately. The module is with high precision, blind spots (3cm) super close. This module provides a full set of ranging process. Model: HC-SR04. Color: blue and silver. Operating voltage: 5V DC. Static current: less than 2 mA. Output signal: Electric frequency signal, high level 5V, low level 0V. Sensor angle: Not more than 15 degrees. Detection distance: 2 cm ~ 450 cm. High precision: up to 3 mm. Mode of connection: VCC / Trig (T) / Echo (R) / GND. Working principle of the module: Adopt IO trigger through supplying at least 10us sequence of high level signal. The module automatically send eight 40khz square wave and automatically detect whether receive the returning pulse signal. If there is signals returning, through outputting high level and the time of high level continuing is the time of that from the ultrasonic transmitting to receiving. Package Included: 1 x ultrasonic sensor module. Review: Great! - Little prone to interference, but I'm sure that's to do with my build. Review: Perfect - Arrived quickly and works perfectly for what I intended. ## Features - Using IO trigger for at least 10us high level signal. - Module can send 8 pro 40 kz square wave automatically, and will test if there is any signal returned. - If there is signals returning, through outputting high level and the time of high level continuing is the time of that from the ultrasonic transmitting to receiving. Test distance = (high level time * sound velocity (340M/S) / 2 - Working Voltage : 5V(DC); Static current: < 2mA; Sensor angle: <15°; Detection distance: 2cm-450cm; High precision: Up to 0.3cm ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01DM8MRTS | | Best Sellers Rank | 80,777 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 33 in Ultrasonic Proximity Sensors | | Guaranteed software updates until | unknown | | Item model number | 1 | | Manufacturer | HALJIA | | Package Dimensions | 7.8 x 6.2 x 1.6 cm; 20 g | ## Images ![HC-SR04 Ultrasonic Sensor Distance Measuring Module Compatible with Arduino - Image 1](https://m.media-amazon.com/images/I/71y8VGiFkqL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great! *by S***E on 15 February 2020* Little prone to interference, but I'm sure that's to do with my build. ### ⭐⭐⭐⭐⭐ Perfect *by E***E on 15 September 2019* Arrived quickly and works perfectly for what I intended. ### ⭐⭐⭐⭐⭐ Review *by K***E on 3 October 2021* rapide et sûr ## Frequently Bought Together - HALJIA HC-SR04 Ultrasonic Sensor Distance Measuring Module Compatible with Arduino - ELEGOO UNO R3 Board for Arduino with USB Cable(Arduino-Compatible) More Faster In Transfer Rates And Better At Storage And Operation --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/48158753-hc-sr04-ultrasonic-sensor-distance-measuring-module-compatible-with-arduino](https://www.desertcart.com.ar/products/48158753-hc-sr04-ultrasonic-sensor-distance-measuring-module-compatible-with-arduino) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-19*
