Keeping the sensor in a fixed position is key to repeatable performance. Review: +/- an inch from a couple inches to across the room. Good enough - Eh, for less than 2.50/sensor it's pretty reasonable accuracy, and pretty easy code for Arduino. If you want mm accuracy this will not cut it. But +/- an inch over several feet is good for the price. ## Features - Test mode :Using IO trigger for high level signal.( Not less that 10us),The Module sends eight 40 kHz automatically and detect whether there is a pulse signal back. - The detection zone: 0.78~196 in/ (2cm~500cm); High precision: up to 0.12 in/(0.3 cm) Effectual angle: less than 15° - Power supply: 5V DC; Quiescent current: less than 2mA. - Test distance = ((Duration of high level)*(Sonic :340m/s))/2 - Package included: 5pcs HC-SR04+ 2pcs Mounting Bracket(support HC-SR04 only) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01JG09DCK | | Best Sellers Rank | #61,560 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #6 in Ultrasonic Proximity Sensors | | Brand Name | Smraza | | Centerline Length | 196 Inches | | Color | Blue | | Connector Type | Plug-In | | Current Rating | 2 Milliamps | | Customer Reviews | 4.7 4.7 out of 5 stars (501) | | Gauge | 10 | | Included Components | 1 | | Item Dimensions W x H | 1.3"W x 0.1"H | | Manufacturer | Smraza | | Material Type | Copper | | Model | S03sF | | Mounting Type | Panel Mount | | Number Of Contacts | 1 | | Number Of Poles | 4 | | Number of Positions | 5 | | Part Number | S03s | | Specification Met | Ma | | UPC | 745360617986 | | Voltage | 5 Volts | ## Product Details - **Brand:** Smraza - **Color:** Blue - **Connector Type:** Plug-In - **Current Rating:** 2 Milliamps - **Gauge:** 10 - **Material:** Copper - **Mounting Type:** Panel Mount - **Number Of Contacts:** 1 - **Number Of Poles:** 4 - **Voltage:** 5 Volts ## Images ![Smraza 5pcs Ultrasonic Module HC-SR04 Distance Sensor with 2pcs Mounting Bracket for Arduino R3 MEGA Mega2560 Duemilanove Nano Robot XBee ZigBee - Image 1](https://m.media-amazon.com/images/I/71U1zi2QigL.jpg) ## Available Options This product comes in different **Number Of Items** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ very useful little kit *by S***E on December 28, 2023* The brackets work much better than some of the cobbled together mounts I've seen.
